12%Cr-15%Mn奥氏体钢是很有前途的核反应堆用材料,但在高温强度和韧性等方面还存在不少尚待进一步改进的问题。为此,研究了钢中C,N,W和V的影响。研究用钢试样由高频感应电炉熔炼,钢中的C,N,W和V的含量分别在0%～0.2%,0%～0.2%,0%～3.5%和0%～0.5%范围内。钢坯经1423～1473 K×3.6 ks均匀化热处理后,热轧成5～15 mm厚板材。制成的试样经1373 K×
12% Cr-15% Mn austenitic steel is a promising material for nuclear reactors, but there are still many problems to be further improved in terms of high temperature strength and toughness. To this end, the impact of C, N, W and V in steel was investigated. The research steel samples were melted by a high-frequency induction furnace. The contents of C, N, W and V in the steel range from 0% to 0.2%, 0% to 0.2%, 0% to 3.5% and 0% to 0.5% Inside. After billet 1423 ~ 1473 K × 3.6 ks uniform heat treatment, hot rolled into 5 ~ 15 mm thick sheet. Made of the sample by 1373 K ×
