The results show that an increase in M&D particulate fraction decreases the grain size of Al matrix due to impeding of particulates against disappearance of grain boundary, and the tensile strengths increase significantly while the elongation first increases and then decreases. Comparatively, the synthesized M&D particulates in this work exhibit a much better toughening effect than CS particulates or traditional monolithic ones. Corresponding strengthening and toughening mechanisms are discussed from the perspective of strength contribution calculation, post-deformed transmission and scanning electron microscopy observations. This work would provide references for conquering the low ductility of metal matrix composites and promotes their widespread application in industry.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"71 1","pages":"4130 - 4143"},"PeriodicalIF":0.8,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86870386","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 was because deposited additive bead often develops defects such as shrinkage, voids, solidification cracking, during liquid to solid transformation. In this study, a low carbon steel double pass additive bead with 32 % lateral overlap was fabricated by the GMAW-WAAM technique followed by hybridization through FSP in the overlapped region (OR). The peak temperature estimation during bead deposition and FSP on bead was done through modeling by using ABAQUS. The microstructural analysis was carried out by using optical microscopy, scanning electron microscopy, electron backscattered diffraction, and transmission electron microscopy. The microstructure of OR of deposited additive bead is dominated by a combination of ferrite and bainite while that of hybrid additive bead (HAB) is dominated by a combination of ferrite and martensite. Further, the analysis revealed the effects of FSP on the OR in the form of grain refinement from 5.56 µm to 3.50 µm and a decrease in the low angle grain boundaries from 35.4 % to 10.6 %. The continuous dynamic recrystallization is observed since the bainitic fraction in the overlapped region decreased along with an increase in the fraction of martensite in the friction stir processed zone. The kernel average misorientation is observed to decrease after FSP from 1.001 of AB to 0.608. The microhardness test reveals the decrease in the hardness after FSP.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"6 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78711721","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}

To assess this interconnection, beam bending was performed using microcantilevers oriented parallel and at 90° to the growth direction. Furthermore, the tests were applied to favour normal bending and shear fracture. Coatings were synthesised by both direct current magnetron sputtering (DCMS) as well as high power pulsed magnetron sputtering (HPPMS). Here, we show that the fracture toughness depends on the alignment of the grains and loading directions. Furthermore, an improved fracture toughness was found in coatings produced by HPPMS, when microstructural defects, such as underdense regions in DCMS deposited coatings can be excluded. We propose indices based on fracture and mechanical properties to rank those coatings. Here, the HPPMS deposited oxynitride showed the best combination of mechanical properties and fracture toughness.

Still, fundamental properties of these materials are understudied. Motivated by this, a series of Cu-containing HA (CuHA) was synthesized via aqueous co-precipitation. Pawley fitting of X-ray powder diffraction (XRD) patterns revealed a dilation of lattice parameters with increasing Cu content, causing a maximum expansion of unit cell volume from 518.2(7) to 528.0(4) Å3. Functional group presence and stoichiometry were investigated using spectroscopic characterization and X-ray fluorescence (XRF), respectively. High-temperature in-situ XRD followed by quantitative phase identification assessed the thermal transition to β-tricalcium phosphate (β-TCP). As Cu target incorporation increased from 0 to 5 mol% (actual 0–1.96 mol%), there was an observable increase in stoichiometry, carbonate removal, and resistance to thermal phase transition. This work also emphasizes the tunability of certain properties through Ca deprivation in the synthesis method. Some key structure–property relationships are identified to build on current understanding of CuHA and its complexities.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":"29 1","pages":"3966 - 3979"},"PeriodicalIF":0.8,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75116341","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 results illustrated the successful preparation of IONPs/F127-FA and its saturation magnetization value was found to be 25.6 emu/g. Moreover, QCT was effectively entrapped into the synthesized IONPs/F127-FA and showed 23.45 ± 7.23% loading capacity and 89.87 ± 2.05% entrapment efficiency. Additionally, the MTT assay revealed that loaded QCT in IONPs/F127-FA showed high inhibition against the human breast cancer cells compared to the free one, which was attributed to the ability to bind to folate receptor α of IONPs/F127-FA.
