Abstract

Abstract

Flow stress curves of stainless 0Cr13 were experimentally studied with a cam plastometer at a constant deformed speed. The effects of the deformed temperature, deformed rate and deformed degree on flow stress were analyzed. At the same time, two non-linear regression mathematical models were proposed. The discrete temperature model fit accurately with the experimental data, and the entire temperature model is useful in the computer control of on-line process.
