Abstract
The purpose of study is to investigate the influence of additional elements (Ni and Cu) on tensile property of Sn-Bi alloys. Tensile tests of Sn-Bi alloys were carried out at various temperature (25, 60, and 80°C) and under strain rates (from 5.25×10-5 to 5.25×10-3 s-1). The tensile strength decreases with decreasing strain rate and with increasing temperature. These results are in good agreement with our previous results. Ni and Cu added to Sn-Bi alloy showed the superplasticity behavior at low strain rate and high temperature (more than 60°C). Moreover, strain rate sensitivity m increases with testing temperature.
