The role of delayed elasticity and stress relaxation in Sn-Bi-Cu lead-free solders solidified under permanent magnet stirring

This paper develops methods to explore the influence of permanent magnet stirring (PMS) on solidification microstructure, thermal behavior and creep parameters of Sn-20Bi-0.4Cu alloys predicted from the primary creep stage at 25 °C. A series of short-term stress relaxation test (SRT) and strain rela...
