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 superior rate performance is mainly attributed to the interface effect of composite material.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"43 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74937383","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 showed that the initial MgO:SiO2 affected the Mg:Si ratio and the binding water content of M-S-H gel. With the decrease of Mg:Si ratio, the proportion of structural water in the gel decreases. Compared with structured water, the change of free water can more accurately characterise the content of M-S-H gel in the system. Below 600°C, the molecular structure and phase composition are relatively stable. When the temperature reached 1000°C, M-S-H gel transfers from amorphous phase to crystallized phase.

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.

In addition, we performed 3D profilometry, microhardness measurements, nanoindentation tests with a Berkovich diamond tip, Daimler-Benz Rockwell-C adhesion, and ball-on-disk wear tests in order to evaluate the mechanical properties.

The dry sliding tribological properties against Al2O3 ceramic and AISI 52100 steel were thoroughly investigated, and the corresponding wear mechanism was explored. The results indicate that the tribological properties of the MoSiBTi alloys are highly dependent on the Ti content and property of counterpart materials. The dominant wear mechanism of the MoSiBTi alloys sliding against Al2O3 ceramic is severe abrasive and adhesive wear and it transforms to mild abrasive and adhesive wear when coupled with AISI 52100 steel. It confirms that the MoSiBTi/AISI 52100 steel friction pairs show more preferable wear resistance, which is more suitable for room temperature tribological applications.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"42 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77081355","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}
