| Abstract: | Isothermal spheroidizing process for H13 hot-working die steel was studied in th is paper.The results show that in t he same processes of quenching and tempe ring,the comprehensive properties of H13 steel pre-treated by isothermal spheroi dizing can be improved for obtaining mor e refined microstructure than that of th e one by normal annealing,and service li fe of the dies can be raised by 50%. |
