Abstract

1. We investigated the effect of the degree and temperature of deformation and the cooling rate on the properties of three heat-resistant alloys subjected to high-temperature plastic deformation. 2. It was found that high-temperature plastic deformation increases the heat resistance of the alloys at moderate temperatures (550°C) when recrystallization is completely or partially eliminated (during its initial stages). 3. High-temperature plastic deformation can be successfully used for articles subjected to moderate temperatures for short periods of time. 4. The fraction of samples subjected to high-temperature plastic deformation is intragranular up to higher temperatures than in samples subjected to the standard heat treatment.
