The Sn-Cu eutectic alloy has been produced by rapid solidification using the melt-spinning technique, and both Zn and Bi have been added individually to it, in the ratio 0.5 wt.%. X-ray diffraction (XRD) analysis and differential thermal analysis (DTA) have been carried out. Resistivity, Vickers microhardness (HV), and yield stress (σ y ) have been measured. Also a new method for measuring creep has been described using a HV tester. The creep measured by this method is termed "microcreep." It is a quick, nondestructive method and requires a small sample, about 1 cm 2 , with thickness 1 mm or less. The results show that formation of Cu 39 Sn 11 occurs due to the addition of both Zn and Bi. The addition of Zn increases HV and σ y , but slightly lowers the creep resistance; however, the addition of Bi deteriorates the creep resistance. Also, it is found that the creep rate of as-quenched melt-spun alloys is high.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
