Abstract
We present the results of investigation of the mechanism of fracture of 14KhN3A, 20, 20KhN3A, 40, and 40Kh steels after hardening and high tempering, and after embrittlement. We show that the intergranular fracture of steels is related to inhomogeneity of the processes of carbide formation on tempering and to the primary carbide separation on the boundaries of grains with elevated energy level. Procedures for thermal treatment are proposed, which enable one to reduce the susceptibility of improved steels to intergranular fracture.
