摘要: 利用Gleeble-1500熱模擬試驗機,研究了9Cr-1Mo-V-Nb-N鐵素體耐熱鋼在850~1250℃,變形速率0.01~10s-1的變形條件下的再結晶行為。獲得了9Cr-1Mo-V-Nb-N鋼熱變形時發(fā)生動態(tài)再結晶的邊界條件,作出了塑性圖和再結晶圖。Abstract: With a Gleeble-1500 thermal simulator,research was made on the recrystallization behavior of the 9Cr-1Mo-V-Nb-N ferrite heat resistant steel under the deformation conditions,i.e.temperature range of 850~1 250℃ and deformation rate of 0.01~10s-1.As a result,the boundary conditions under which recrystallization of the said steel occurs during thermal deformation thereof was obtained and the plasticity chart and the recrystallization chart produced.
