STRUCTURE AND PROPERTIES OF DOPED WITH NITROGEN AND VANADIUM HIGHCARBON STEELS
The results of investigations of structure and properties tensile and compressive of highcarbon hypoeutectoid and eutectoid steels in the conditions of cyclic thermal and force action depending on the type of structure (pearlite, bainite, martensite), shape, dispersion and cementite particle distribution are given. It is shown that the reduction in cyclic durability of steels with martensite and bainite structure due to of coagulation of cementite phases. There is a significant increase the thermal cycling durability of the steels with pearlite structures.
