The purpose of study is to investigate the influence of testing temperature on tensile property of Sn-Bi alloys. Tensile tests of Sn-Bi alloy were carried out at various strain rates from 5.25×10^<-3> s^<-1> to 5.25×10^<-1> s^<-1> over temperature range from 25℃ to 80℃. Based on the experimental data, the specimen gave the highest strength at the fastest strain rate and at room temperature of 25℃. The lowest strength occurs when the specimen is subjected to the slowest strain rate at 80℃. The tensile strength decreases with decreasing strain rate and with increasing temperature. Moreover, strain rate sensitivity m increases with testing temperature.
