In the present study, the transient, and steady state creep of Sn-9Sn and Sn-9Sn-0.7Cuternary alloy was investigated in the temperature range from 323, to 403 K at different five stresses ranged from 3.62 to 11.22 MPa.The transient creep parameters n and β were found to be markedly affected by the creep test conditions, T and ϭ.The parameter β was found to be increased by increasing transformation...
