Effect of Adding Bismuth on Some Mechanical Properties of Ga Alloy

This work involves addition of Bi nanopowder to Ga alloy to improve some mechanical properties. These properties included hardness, compression, tensile strength and creep. The characterization of prepared Bi/Ga alloys with 5 wt% of Bi (1, 2, 3, 4 and 5 wt%) was done by XRD and SEM/EDS. The results showed that the hardness, compression and diametral tensile strength were increased with increasing wt% from 1 to 5% of added Bi, while creep decreases due to increase in the crystallization site and the formation of BiIn2 phase. © 2019, Springer Nature Switzerland AG.
