摘要：

The application of ultrasonic vibration in metal forming is attracting more attention due to the better performance of ultrasonic-assisted process. By adding small vibration amplitude on tools, the plastic deformation behavior of metal material would differ from the static process. In this study, ultrasonic-assisted compression test was carried out to investigate the influences induced by ultrasonic systematically Ultrasonic influences on material flow stress, friction and temperature were analyzed Acoustic softening effect was found size dependent and a new model on basis of surface grain model was proposed to explain it. Numerical simulations were carried out to validate and compare with experimental results.
