Abstract
Extensive use of die casting is limited by the short operating life of molds with cyclically changing temperature and stresses. As a result of this action there is thermal fatigue failure of the operating surfa ce layer er of a mold. This article considers features of the thermal fatigue failure mechanism for steels 3Kh2V8F and 4KhSMFS used for mold manufacture.
