Abstract

Dynamic recrystallization processes in heat-resistant Ni-based alloy was investigated depending on temperature, strain rate and deformation ratio. Recrystallization intensity is determined by the temperature and deformation conditions. The factors that increase the degree of dynamic recrystallization include temperature and amount of strain increasing, as well as decreasing of strain rate. Increasing the volume fraction of recrystallized structure causes a uniform fine-grained structure. Detailed microstructure analysis of heat-resistant Ni-based alloy after dynamic recrystallization was performed.

Keywords: dynamic recrystallization, heat-resistant alloy, Ni-based alloy, stress-strain curves, slip lines, twinning
