抄録

Pine cone fracture surfaces were observed in Charpy and compact tension specimens of cryogenic Ni steels containing retained austenite. These steels, especially those bearing no molybdenum, were embrittled on slow cooling from final tempering. ″Pine cone″ is a kind of intergranular fracture surface produced by fracture along P segregated alpha prime / gamma interfaces which formed at prior austenitic grain boundaries. Intercritical heat treatment promoted austenite formation and suppressed fracture.
