Microstructure analysis showed that the matrix of the coposites was mainly composed of Ti 3 SiC 2 , SiC, TiSi 2 and little amount of residual Si and C. The composites achieved the highest mechanical performance when the Ti 3 SiC 2 content was the highest. The high-temperature oxidation results indicated that even after 100 h of oxidation at 1300°C, the bending strength of the composite material can still maintain 83% of its initial strength compared to other composites. This may be due to the formation of SiO 2 and TiO 2 oxide layers by partial oxidation of Ti 3 SiC 2 in the matrix, which will protect the composite material from further oxidation.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147907455","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}

FTIR, TGA, and water contact angle measurements confirmed the successful synthesis and performance enhancement of MGCC. The mechanical properties, dynamic mechanical analysis, thermal stability, and heat resistance were also analyzed to evaluate MGCC/PVC composites. The results indicated that MGCC exhibited strong interfacial compatibility with PVC, significantly enhancing the mechanical properties of the composite material.

Eu@HEr exhibited a 42% increase in tensile strength (86 MPa) and a 114% improvement in elongation at break (10.9%) compared to EPI.

The results showed that the well-bonded Fe-based coatings with the addition of MgAl 2 O 4 particles were successfully prepared by laser cladding. The addition of MgAl 2 O 4 particles promoted the formation of other hard-reinforced phases, such as Fe 3 Al and (Fe, Cr) 7 C 3 , playing an important role in grain refinement. Compared with the Fe-based coating, the hardness and abrasion resistance of Fe-based coatings with 30 wt% MgAl 2 O 4 were evidently enhanced, which is attributed to the more hard-reinforced phase's dispersion strengthening and grain refinement.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"41 16","pages":"1204-1215"},"PeriodicalIF":0.0,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147896614","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}

Based on the plastic strain energy density theory of mashing behaviours, the values of parameters K and n in the Ramberg–Osgood stress–strain relationship were obtained. The Coffin–Manson model was modified for further modelling of specimens exposed to different temperatures. A fitted formula for the relationship between the plastic strain energy density and fatigue life of HTRB630 high-strength steel bar specimens was established. The parameters obtained in this study can provide a reference for further investigation of the seismic performance of HTRB630 steel bars reinforced concrete structures after exposure to high temperatures.KEYWORDS: HTRB630 high-strength steel barshigh temperature exposurelow-cycle fatigue propertymashing behaviourmodified Coffin–Manson model AcknowledgementsThis research has been supported by China Scholarship Council; the Natural Science Research Project of Jiangsu Province Colleges and Universities (21KJD560002), China; Suqian Natural Science Foundation Project (K202012), China; Project funded by the research and innovation team of engineering structure seismic technology of Suqian University in 2020, China; Suqian City Guiding Science and Technology Plan Project (Z2020137), China; Research and Innovation Team Project of Suqian College (2021TD04), China; and the Fifth Provincial Research Funding Project of ‘333 High-level Talent Training’ in 2020 (BRA2020241), China; The Youth Fund Project of Suqian College (2023XQNA03).Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by Project funded by the Research And Innovation Team of Engineering Structure Seismic Technology of Suqian University in 2020, China; Suqian City Guiding Science and Technology Plan Project [grant number Z2020137]; the Natural Science Research Project of Jiangsu Province Colleges and Universities [grant number 21KJD560002]; The Youth Fund Project of Suqian College [grant number 2023XQNA03]; China Scholarship Council; Suqian Natural Science Foundation Project [grant number K202012]; the Fifth Provincial Research Funding Project of “333 High-level Talent Training” in 2020 [grant number BRA2020241]; Research and Innovation Team Project of Suqian College [grant number 2021TD04].","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135397238","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}

Point contact interfaces in composites are constructed by growing of Mn3O4 nanoparticles on the surface of acetylene black (AB). The prepared electrode materials exhibit excellent rate capability (355.7 mAh g−1 at 6.4 A g−1) and cycling stability (1386.7 mAh g−1 after 300 cycles at 1 A g−1). The presence of AB in the composite reduces the charge transfer resistance and improves the cycling stability of the electrode. Moreover, the interface between the composites increases the contribution of pseudocapacitance, which will facilitate the electrode kinetics. The construction of interfaces in the composites provides a promising perspective for the design of high-power density anode for LIBs. Highlights Construction of Mn3O4 nanoparticles on 0 D-AB spheres was proposed and synthesised by a facile and scalable strategy. The composite materials exhibit excellent electrochemical performance.

The sliding wear resistance was therefore increased by 76, 76, and 85% under applied loads of 5, 10, and 20 N, respectively. The average friction coefficient (AFC) of CP-Ti also reduced considerably by the FSS. For instance, the AFC was reduced from 0.67 ± 0.07 and 1.04 ± 0.14 to about 0.33 ± 0.03 and 0.45 ± 0.04 at the applied loads of 5 and 20 N, respectively.
