NATURE OF DELAYED FRACTURE OF QUENCHED STEEL

The fracture of steel quenched to martensite under the influence of static stress is called delayed fracture. It is often the reason for premature failure of quenched steel machine parts, the formation of cracks in welds, steel bars, etc. The authors investigated the reasons for the formation and growth of cracks during delayed fracture of steels 40Kh2N5SM (0.39% C, 0.95% Si, 0.05% Mn, 5.1% Ni, 2.1% Cr, 1. 2% Mo) and 18KhNVA (0.19%C, 0.52% Mn, 1.61% Cr, 4.47% Ni, and 0.84% W).
