本文研究了临界点间热处理对新钢种20CrMnSiNi2A钢的第二类回火脆性及对两种钢(20CrMnSiNi2A钢和D6AC钢)第一类回火脆性的影响。结果表明:临界点间热处理不仅可减小钢的第二类回火脆性,也可抑制钢的第一类回火脆性。
In this paper, the second type of tempering brittleness of the new type of 20CrMnSiNi2A steel and the influence of the first type temper embrittlement on the two types of steels (20CrMnSiNi2A and D6AC) were studied. The results show that the critical point between the heat treatment not only can reduce the second type of temper brittleness of steel, but also inhibit the first type of temper brittleness.
