A multi-criteria decision-making approach was employed to identify the optimal energy-absorbing architecture. The SNT structure, with the smallest gap size between the inner and outer tubes, exhibited the most desirable energy absorption characteristics among the considered cases. Acrylonitrile butadiene styrene (ABS) cores, with either rhombic or square cell configurations, were used to enhance the energy absorption performance of the SNT structure. A finite element model was created to evaluate the responses of the SNT structure filled with ABS cores. The validity of finite element simulations of the ABS cores and optimal architecture under axial compression were confirmed by comparing them with experimental results. The integration of the cores into the nested architecture enhanced crashworthiness performance and contributed to the control of the structure deformation. The SNT structure filled with rhombic ABS core exhibited superior crashworthiness performance compared to the counterpart filled with square core. The energy absorption of nested SNT structures filled with rhombic ABS core can be 116.93% greater than the corresponding non-filled structure. The crashworthiness indices of ABS-filled structures were highly sensitive to the number of cells and wall thickness of the core. A nested architecture with an ABS core could serve as a novel architecture for energy-absorbing devices.","PeriodicalId":20630,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim is to comparatively assess the mechanical and morphological characteristics of these composite structures. The comparative analysis also included variations in the skin thickness of the sandwich composite. Mechanical tests such as compressive, impact, and hardness were carried out. Moreover, fracture tests specifically focusing on single-edge notched beam fracture (mode I) were conducted under different temperature conditions, low (−10 °C), ambient (25 °C), and high (100 °C) temperatures. Comparative analysis of the mechanical properties indicated that the isophthalic-based sandwich composites exhibited superior mechanical characteristics when compared to their orthophthalic counterparts. Fracture properties of both types of sandwich composites demonstrated higher values at lower temperatures, followed by room temperature, and then high temperatures. In both types of sandwich composites, using two layers of E-glass on both sides of the polyvinyl chloride foam resulted in superior properties. This improvement can be attributed to the increased skin thickness. The interfacial properties were identified using Fourier transform infrared spectroscopy and scanning electron microscopy, revealing distinct spectroscopic features such as CH-stretching, C–O–C, CH bend, CN stretching, and NH stretching. Examination of the fractured surfaces through scanning electron microscopy revealed distinct features such as crushed fiber, fiber pull-out, honeycomb, riverline patterns, matrix-fiber delamination, and debonding, providing valuable insights into the composite's structural integrity.","PeriodicalId":20630,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141785635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of innovative ultrasound-assisted milling processes and plasma-welded nickel- and cobalt-based wear protection coatings are being investigated to determine how more favourable machinability can be achieved while retaining the same wear protection potential. The focus is on the NiCrSiFeB alloy, which is intended to replace CoCr alloys in the area of screw machines. The utilization of ultrasonic-assisted milling for the machining of coating materials is a novel approach. The modification of hard facing layers in terms of microstructure and precipitation morphology as well as suitability for machining is investigated and compared with the CoCr alloy. The alloy modifications are generated by a PTA process by systematically adjusting the preheating and interpass temperatures, a crack-free wear-resistant layer can be generated, which is subsequently machined by a milling process. In addition to the crack-free properties, the microstructure, the bonding as well as the mixing between the NiCrSiFeB alloy and a 1.8550 as well as between the CoCr alloy and a 1.4828 are analysed and compared in the joining areas. In addition, heating and cooling rates are determined and a chemical analysis of the weld metals is performed. Furthermore, it was found that the build-up layers of NiCrSiFeB alloy are more difficult to machine using the milling process than the CoCr alloy, as higher milling forces are required.","PeriodicalId":20630,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141785637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary purpose of this study is to explore the influence of wire core diameter on the performance of ultrasonic welded joints. Wire core diameter is positively correlated with the peeling resistance of the joint. Superior mechanical properties of the joint are achieved with an increased diameter of the wire core. The peeling strength of the welded joint of two wires with a wire core diameter of 0.25 mm reaches 306.8 N. Examining the welding temperature and assessing the joint's porosity reveals a significant impact of temperature on porosity. However, relying solely on porosity as a criterion for judging the overall forming quality of joints may be insufficient. Scanning electron microscope and energy-dispersive X-ray elemental analysis revealed that certain wires underwent plastic deformation at elevated temperatures without attaining atomic bonding. Additionally, the welded joint exhibits a compact structure externally and a more relaxed structure internally. The upper side of the joint in contact with the briquette and the lower side in contact with the welding head exhibit minimal gaps, while numerous gaps are evident in the middle of the joint. Furthermore, upon examining the fracture morphology, two distinct failure modes are identified at the joint surface of the conductor. The first involves the fracture of the wire core with a completely separated joint surface, resulting in poor mechanical properties of the joint. The second mode entails the ductile fracture of the wire core at the joint surface, indicating good mechanical properties of the joint.","PeriodicalId":20630,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evolving microstructure and time to peak hardness during aging are vital for creating high-strength alloys. The electrical conductivity variation over time is utilized to analyze the diffusion process governing the clustering and growth of specific phases (η′, η, and S) during artificial aging. The paper demonstrates the impact of GP zones, precipitate formation, and grain growth on electrical conductivity, correlating these factors with hardness, microstructure, and tensile strength to determine the hardening stage. Differential electrical conductivity plots, highlighting aging stages, assist in identifying the hardening phase. Tensile strength and hardness plots differentiate the precipitation phases. The Johnson–Mehl–Avrami–Kolmogorov equation models particle growth kinetics, determining growth rates for AA 7050 alloy.

Research work on the burnishing process is numerous. However, the reports containing the comparative investigations are lacking. In this work, the effect of ball burnishing parameters namely penetration depth, burnishing spindle speed, and number of passes has been compared and analyzed on AISI 1045 and AISI 304 steels with respect to surface roughness, hardness, wear resistance, and corrosion resistance. Results indicate that the combination of a feed rate of 0.12 mm/rev, spindle speed of 160 rpm, and penetration depth of 0.025 mm with four passes generated minimum surface roughness (AISI 1045). However, maximum surface hardness is obtained with a feed rate of 0.12 mm/rev, spindle speed of 160 rpm, and at 0.085 mm penetration depth under one pass (AISI 304). The lowest specific wear rate is achieved with a feed rate of 0.12 mm/rev at a spindle speed of 160 rpm and a penetration depth of 0.085 mm in one pass (AISI 304). The burnishing process influenced both materials, AISI 304 and AISI 1045, under varying parametric conditions. The maximum reduction in surface roughness is 68.1% for AISI 304 and 79.3% for AISI 1045, while surface hardness improves by 27% for AISI 304 and 22% for AISI 1045. Additionally, the burnishing process reduces the specific wear rate by 49.3% for AISI 304 and 45.4% for AISI 1045. The refinement of grains during the burnishing process enhances corrosion resistance compared to the unburnished surface.","PeriodicalId":20630,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This demands significantly improved design of welded connections for thermo-mechanical fatigue (TMF). A common mode of high temperature failure for welded 9Cr steels in such plant is Type IV failure, due to reduced hardness in the inter-critical heat affected zone (IC-HAZ). Little or no work has been previously conducted on TMF characterisation of HAZ of 9Cr steels. This work presents development of a combined Gleeble physically-simulated welding process for P91 heat affected zone, based on measured thermal histories from bead-on-plate welding trials, with in-situ low cycle thermo-mechanical fatigue up to 650°C. The simulated welding process, including post-weld heat treatment (PWHT), is shown to have significant effect on both microstructure and TMF behaviour, including life. The as-welded condition is shown to have the cyclically hardest stable response and the longest life, whereas the PWHT and parent material (PM) cases have similar cyclically soft responses and lives. A recently-developed through-process, physically-based, thermal-metallurgical-mechanical model is adapted and applied to the simulated welding thermal cycle and TMF testing for PM and HAZ specimens. The model is calibrated and validated against high temperature low-cycle fatigue and low-cycle TMF data for PM in the range 400 to 600°C, for different strain-ranges and strain-rates. It is also shown to capture some observed general trends for the simulated HAZ-TMF testing, especially the significant softening effect of PWHT and the significant increase in cyclic strength for the as-welded condition.","PeriodicalId":20630,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141349612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
