Abstract

The deformation behavior of a 4032 aluminum alloy by hot compression has been investigated. It was found that the flow stress was strongly dependent on temperature as well as strain rate. The strain rate-sensitive coefficients were calculated at different temperatures. The experimental stress-strain data are fitted by means of the model earlier advanced by Sah et al. The Sellars-Tegart-Garofalo (STG) model is used to obtain activation energy values, which vary with the strain rate and strain.
