Influence of preliminary ultrasonic treatment upon the steady-state creep of metals of different stacking fault energies

• We model the steady-state creep of metal as a function of preliminary ultrasonic irradiation.
• We model how the stacking fault energy of metal affects the above phenomenon.
• We use the synthetic theory of irrecoverable deformation to model the phenomena above.

This paper addresses the issue of the ultrasound effects upon the creep deformation of metals with different levels of stacking fault energy. The influence of preliminary ultrasound irradiation time upon the steady state creep rate is considered. Synthetic theory of irrecoverable deformation is taken as a mathematical apparatus. The analytical results show good agreement with experimental data.
