Abstract
Hot compression tests on super austenitic stainless steel (SASS) are performed in the temperature range of 900–1200 °C and strain rates of 0.01–10 s−1. The results reveal that, at lower deformation temperatures of 900 and 1000 °C or lower strain rates of 0.01 s−1, 0.1 s−1 and 1 s−1, the dominant DRX mechanism of SASS can be summarised as: a large number of high-angle grain boundaries (HAGBs) are gradually developed from low-angle grain boundaries (LAGBs) and DRX grains are partially formed on HAGBs. However, the formation of DRX grains due to sub-grain rotation is the main DRX mechanism at higher temperatures of 1100 °C and 1200 °C and at the higher strain rate of 10 s−1.
