This paper reviews the high-speed deformation test methods and techniques at high strain rates of 10 ~ (2 ~ 3) s ~ (-1) at home and abroad, and the progress and current status of metal rheological behavior under high strain rates in China. The article also outlines the technical performance and main features of high-speed deformation machine developed by our country. Modern metal pressure processing, with the development of new technologies and the needs of production, Japan gradually toward the direction of high-speed development.
