The hot deformation behavior of superaustenitic stainless steel S32654 was studied in the temperature range of 950-1200 degree C and strain rate range of 0.001-10s-1 employing hot compression tests. The results show that peak stress increases with decreasing of temperature and increasing of strain r...
