Abstract

A finite element analysis has been conducted to simulate direct/indirect extrusion process for AZ31 Mg alloy at various ram and die speeds. Uniaxial compression test on AZ31 Mg alloy was carried out at various strain rates and temperatures and the result was used as input data fur finite element analysis. It was found that ram speed affects the distribution of dead zone area during direct extrusion. The inhomogeneous temperature and strain distributions through the thickness direction can be simulated under the various extrusion process conditions.
