The optimum combination of texture density and self-lubricating mechanism of IMBSC were studied. The results show that the tribological properties of IMBSC are strongly dependent on the synergistic lubrication effect of SnAgCu and biomimetic shell-like micro-texture.

This alloy gets its hardness from the precipitation of the α phase in the <i>β</i> matrix. The focus of this investigation is to determine how high-temperature aging affects its microstructure evolution. Various thermal aging tests have been performed in a horizontal tube furnace in an inert gas environment for up to 6 h from 450 °C to 700 °C with a step gap of 50 °C. After each heat treatment, the resulting microstructure and associated phase change and composition have been analyzed and reported by making use of a scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD) techniques. Results show that the supersaturated <i>β</i> phase obtained after solution treatment at 800 °C gives way to the more stable α phase during aging and that the α phase fraction rises as the temperature increases with accelerated precipitation at 500 °C and 550 °C. Raising the aging temperature and prolonging the duration results in the formation of α phase precipitates at grain boundaries and within the grains themselves. This transition is accompanied by a shift in morphology from globular to lath-shaped. EDS mapping, together with SEM observation, points to the α phase becoming coarser and less dense with a further rise in aging temperature to 600 °C and beyond. XRD analysis of the aged samples detects the presence of only hcp α and bcc <i>β</i> with <i>β</i> phase split taking place at 500 °C. Aged samples displayed a gradual increase in Vickers hardness, reaching a maximum before subsequently decreasing. This observation aligns with the concept that mechanical properties evolve in tandem with microstructural changes. The most favorable properties were achieved following a 6 h aging process at temperatures of 500 °C and 550 °C.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 18","pages":"19945 - 19956"},"PeriodicalIF":2.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090462","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}
