Abstract

Work is devoted to selecting parameters for a hot plastic deformation regime for alloy KhN55MVTs-ID on the basis of analyzing a distribution map for mechanical energy dissipation coefficients. The map is constructed from results of simulation modeling of deformation regimes for alloy samples in the temperature range 900–1140°C and strain rates of 10–3–10 sec–1. Metallographic analysis and a study of the sructure using electron microscopy are used for dissipation coefficients close to extreme values. The expediency of using a map for the process of finding favorable conditions for hot plastic deformation of alloy KhN55MVTs-ID is demonstrated.
