The as-printed IN718 samples are subjected to solution treatment at 1050 °C, two-step precipitation hardening (@ 720 °C for 8 h and @ 620 °C for 8 h), and low plasticity burnishing. Two different sequences were attempted. Sequence-1 involves solutionizing → low plasticity burnishing followed by precipitation hardening, and sequence-2 includes solutionizing → precipitation hardening followed by low plasticity burnishing. The experimental observations and detailed investigations revealed that the samples processed via sequence 2 exhibited a better surface finish. The microhardness of the samples of sequence 2 is 10% higher than their counterparts in sequence 1. The maximum residual stress of −1375.33 MPa is obtained in sequence 1 as compared to the residual stress of −1100.67 MPa in sequence 2. The influence of the processing sequences on the surface properties has been discussed in detail using the XRD and microstructural characterization supported with EBSD analysis.<h3 data-test=\"abstract-sub-heading\">Graphic Abstract</h3>\u0000","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"11 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206405","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}

Low-density steels with compositions of Fe-18.93%Mn-6.20%Al-0.76%C (Steel A) and composition of steel A, with the addition of 2.5 %Ti and 0.5 %C are melted via induction melting and cast into copper mold to get austenite in steel A and austenite plus in-situ formation of 4.5 vol% TiC in Steel B, respectively. Both the homogenized steels are subjected to hot rolling followed by solutionizing and quenching in water. The austenitic Steel A reports low density and Young’s modulus of 6.99 g/cc and 169 GPa, respectively. The presence of 4.5 vol% TiC in austenitic Steel B reduces density to 6.84 g/cc but increases Young’s modulus to 176 GPa, yield strength to 578 MPa, and tensile strength to 920 MPa. In situ formation of TiC increases grain boundary strengthening due to refinement in austenite size and dislocation strengthening significantly even though solid solution strengthening is the dominating one. Formation of TiC reduces the product of strength and elongation (PCE) to 32.5 GPa% due to a decrease in ductility. Both steels exhibit Ludwigson flow behavior, characterized by two distinct slopes of easy glide and cross-slip, respectively, in true stress–true strain plots.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"8 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206402","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}

For this purpose, mixtures of pure Ni, Al, Ti, and B powders were milled in a ball mill for 20 h to produce NiAl-TiB2 nanocomposites containing 10, 20, and 30 at% TiB2. The heat treatment temperature was selected at 850 °C for 30 min which was determined by differential thermal analysis. X-ray diffractometer (XRD) was used to identify the existing phases. The XRD results showed the completion of alloying after heat treatment. Furthermore, the morphology of the powders and microstructure of the sintered samples were investigated by optical microscopy and field emission scanning electron microscopy. Results showed that the NiAl-20% TiB2 sample had the most homogeneous morphology. Then the powder mixture was hot pressed at 800 °C under 300 MPa. The density of the sample reached 95% after hot pressing. The sample containing 20% TiB2 was subjected to wear test under 5, 7, 10, and 13N loads by pin on disk method. Examination of the morphology of the worn surface and wear debris showed that spalling was the dominant wear mechanism.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"67 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206256","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}

Fe–Co–B ternary alloys with varying boron concentrations between 0 and 2 wt% were synthesized through mechanical alloying. The study aims to analyze the structural, morphological, and magnetic properties of the Fe–Co alloy matrix with the inclusion of boron. The XRD results showed a single solid solution phase of Fe–bcc structure for all alloys, regardless of the boron concentration. It was seen that the low solubility of boron in Fe–Co caused the formation of hard structures at the grain boundaries, resulting in an increase in hardness with an increase in boron concentration. On the other hand, a decreasing trend was observed in coercivity, which is ascribed to the formation of FeB at the grain boundaries, as proved from XRD analysis. An increase in boron concentration did not seem to significantly affect the saturation magnetization, which remained in the range of 190 ± 10 emu/g for all Fe–Co–B alloys. The experimental data was cross checked and further insights were gained; DFT calculations were performed using Vienna Ab Initio Simulation Package.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"57 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206403","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}

Additive manufacturing (AM), specifically selective laser melting (SLM) is useful for porous scaffolds fabrication where complex passages facilitaes bone re-growth. This study focused on the modeling, manufacture, and testing of microstructure and mechanical characteristics of seven different scaffolds (Diamond, Cross, Grid, Vinties, Tesseract, Star, and Octet) of 15 mm cube with 65% porosity. Average pore area and strut thickness of scaffolds are measured using Stereo microscope. All these fabricated scaffolds are experimentally tested under compressive loads in INSTRON testing machine. The compressive test results are also compared with the numerical simulation results generated using finite element analysis (ANSYS) software. Maximum load cell capacity of ± 25 kNis used during compression testing in INSTRON. The Grid type scaffold shows maximum ultimate compressive strength of 101.39 MPa and an effective elastic moduli of 10.33 GPa with an average pore area of 2,417,618.517 µm2 and strut thickness of 740.249 µm. This variant of the scaffold will be more compatible with the human bone’s elasticity, and it can also mitigate stress-shielding effects during healing.","PeriodicalId":23224,"journal":{"name":"Transactions of The Indian Institute of Metals","volume":"69 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142206249","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}
