Within the model, six main groups (including a total of 31 properties) are defined: economic aspects, design and production properties, mechanical properties, physical properties, chemical properties and biological properties. A risk-based fuzzy decision making framework is proposed for prioritization. First, a risk-management decision matrix is created by employing interval type-2 fuzzy failure modes and effects analysis. Afterward, the properties of cobalt–chromium alloys are analyzed by utilizing interval type-2 fuzzy measurement of alternatives and ranking according to compromise solution. In the last phase, a prediction model is devised with an adaptive network fuzzy inference system to save computational time and effort and to enable the incorporation of new scientific results into the biomaterial evaluation process. The results of the current study demonstrate that compatibility, osseointegration, corrosion resistance, fatigue resistance and time-dependent deformation are the top five properties contributing to potential orthopedic implant failures and risks. Furthermore, the developed model produces very satisfactory results with acceptable deviations. Consequently, this study presents a new and reliable guide for the unbiased evaluation of cobalt–chromium alloys.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":"72 1 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138528404","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 of this work is to fabricate graphene-reinforced poly(lactic acid) (PLA/Gr) scaffolds with different pore shapes (circular, square and hexagonal) and different pore sizes (1000, 1500 and 2000 μm) using the fused deposition modeling process. The characteristics of the three-dimensionally (3D) printed PLA/Gr scaffolds were analyzed through Fourier transform infrared spectroscopy, thermogravimetric analysis, derivative thermogravimetry, scanning electron microscopy and energy-dispersive X-ray spectroscopy. The water contact angle measurement showed a hydrophilic surface (70 ± 2.7°) for scaffolds with a pore size of 1000 μm. Mechanical property studies showed that the scaffold with circular 1000 μm pores had a compressive strength of 18.53 ± 0.90 MPa, which was similar to the cancellous bone value. In addition, this study involved an examination of the in vitro bioactivity, water uptake and biodegradation characteristics of the scaffolds. The results reveal that the 3D-printed PLA/Gr scaffold featuring a circular pore shape with a pore size of 1000 μm exhibits great potential as an implant for BTE.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":"29 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138528403","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 structural analysis revealed the presence of a cubic CdS lattice with a hexagonal FeS phase in Cd1-xFexS nanoparticles. XRD results showed that the FeCl3 dosages had a significant influence on the formation of ternary Cd1-xFexS nanoparticles. The morphological analysis indicates that the Cd1-xFexS nanoparticles have a spherical shape with a size of approximately 20 nm, while CdS nanoparticles have a size of approximately 12 nm. The optical characterization revealed that the bandgap of pristine CdS and Cd1-xFexS nanoparticles decreased with an increase in Fe content. The bandgap of Cd0.8Fe0.2S was slightly higher than that of CdS, while the bandgap of Cd0.6Fe0.4S and Cd0.4Fe0.6S nanoparticles were lower than that of CdS. The energy band structures of pristine CdS and Cd1-xFexS nanoparticles were calculated using density functional theory and were compared with experimental results. In summary, this work presents a detailed investigation of the structural and optical properties of Cd1-xFexS nanoparticles synthesized using a cost-effective chemical technique.

Compression tests were conducted to determine the compressive strength of BCHB. Furthermore, the compressive and heat transfer properties of these blocks were investigated with finite element analysis, and the following results were observed. 1) The BCHB model did not easily experience local collapse, and instead, it mainly exhibited thin cracks due to shear failure, providing great cracking and collapse resistance, thereby resulting in excellent compressive performance. 2) By reducing the thickness of the short edges of the BCHB models, they exhibited great compressive and thermal insulation performance, making these the preferred BCHBs. 3) The BCHB presented herein is the simplest model of the beetle elytron plate. In contrast to a traditional hollow brick, the BCHB is proven to be a lightweight, fully enclosed brick (block) with a high hollow ratio and can be used as a new nonbearing wall material replacing the traditional type in building construction.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47422589","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}

Compared to other pure coppers, ETP copper has lower weldability. Therefore, this study analyzes the weldability of ETP copper using the Gas Tungsten Arc Welding (GTAW) process. GTAW can be performed using Constant Current (CC) and Pulsed Current (PC) modes. Consequently, the properties of the joints fabricated using both modes are compared and analyzed in this study. The results show that the joint efficiencies of GTAW-CC and GTAW-PC joints are 81% and 89%, respectively. The optimal heat input and pulsating action in pulsed current mode produce refined grains in the weld zone and heat-affected zone, resulting in higher joint efficiency.","PeriodicalId":11537,"journal":{"name":"Emerging Materials Research","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45862083","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}

As-cast ZMG610 alloy was mainly comprised of α-Mg matrix, Mg7Zn3 phase and Mg3Zn6Gd (I-phase), large number of I-phase particles remained in the matrix after homogenization treatment at 330 °C up to 24 h. As-extruded ZMG610 alloy exhibited a bimodal structure consisting of fine dynamically recrystallized grains with wide orientation spread and coarse un-dynamically recrystallized grains with strong basal texture. All as-extruded samples exhibited typical basal texture with basal plane of most grains paralleled to extrusion direction (ED). The lower texture intensity could be obtained through the increase of both extrusion ratio and temperature. Optimal mechanical properties (YS of 267 MPa, UTS of 360 MPa and EL of 14.2%) were obtained through the combination of low temperature (350 °C) and high extrusion ratio (45).

The elastic modulus examined by the nanoindentation method of static mechanical analysis was taken as the output response variable. The optimum levels of mixing time, mold temperature, mold pressure, and holding time process parameters for maximum elastic modulus were found to be 90 minutes, 400 °C, 150 bar, and 15 minutes, respectively. The ‘Analysis of Variance’ technique analyzed that the mold temperature had the highest contribution (46.82%) in enhancing the elastic modulus to the largest value. The elastic modulus and hardness of PEEK-based hybrid nanocomposite with 30 wt.% nHA and 3 wt.% MWCNTs were observed to be 83% and 65% more than that of pure PEEK.
