| Abstract: | A set of new nitrogen-containing hot work die steels were designed.The best composition of experimental steels was optimized by microstructure,mechanical properties and thermal fatigue tests.Then heat treatment processes of the best composition steel were optimized.The results show that the best compositions of V,Cr,N are 1.0wt%,3.75wt% and 0.01wt%,respectively.The optimized heat treatment process for the best composition steel is that quenching at 1080 ℃,first tempering at 550 ℃ and second tempering at 530 ℃. |
