Here, by employing titanium/steel as a model system, the effect of covering thickness on microstructures and mechanical properties of the bonding interface was systematically investigated. It was found that all the welds displayed wavy interfaces, and the wave size increased with increasing covering thickness. Vortices characterized by solidified melt zones surrounded by strongly deformed parent materials, were only formed for the welds performed with a covering. Moreover, with increasing covering thickness, both the tensile strength and the elongation of the titanium/steel plate decreased, and the failure mode changed from ductile to cleavage fracture, gradually. In the tensile-shear tests, all the fractures took place in titanium matrix without separation at interface, indicating that the titanium/steel interfaces had an excellent bonding strength. The micro-hardness decreased with increasing distance from the interface, and this trend was more remarkable for a thicker covering. The micro-hardness inside the solidified melt zones was far higher than that observed in strain-hardened layers of the parent metal, due to formation of hard intermetallic compounds.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138962649","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 trend for slag and alloy component under different batching conditions are in good agreement with experiment, while the difference between the theoretical calculation and experiment can be attributed to the deviation from the thermodynamic equilibrium. The modified mass action concentration model with melts and slag can be used to predict the composition and content of the system when equilibrium is achieved at a certain temperature under a specific material ratio, which is conducive to reducing the cost of the experiment and predicting the operability of the actual process. Moreover, it is believed that this thermodynamic insight may has certain application prospects in these metallurgical procedure based on the equilibrium process.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138994557","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}

Therefore, this paper reviewed the effect of moisture content and temperature on the tensile strength of potential natural fibres for engineering purposes. Furthermore, this paper also critically reviewed the influence of alkaline treatment on natural fibres’ tensile strength. This is significant because alkaline treatment enhances surface friction and the fraction of the revealed cellulose on the fibres’ surface, resulting in better mechanical interlocking. In conclusion, natural fibres demonstrate their potential for geotechnical applications due to the materials’ strong tensile properties after being subjected to treatment processes.","PeriodicalId":8304,"journal":{"name":"Archives of Metallurgy and Materials","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138959545","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 research results show that the tensile strength and hardness of the carbon nanotube composites with different contents will be improved, but to a certain extent the elongation of the composite material will be reduced, and there is an optimal addition amount. The mechanical properties of composite materials prepared by adding CnTs with relatively small length and diameter are better.
