Abstract

The compression of cylindrical samples 15 mm in diameter and virtual billets 150 mm in diameter made of a VT20 alloy and having various ratios of the initial sizes is simulated under similarity conditions. The influence of a nonuniform distribution of the average stress and the cumulative strain, as the factors that determine the microstructural heterogeneity, is discussed.
