EFFECT OF THE TECHNOLOGICAL PARAMETERS OF TREATMENT ON THE MECHANICAL-PROPERTIES OF BORON-CONTAINING STEELS FOR COLD DIE FORGING

Widening of the production of industrial holders and fasteners made of boron-containing steels and the absence of clearly formulated recomme ndations on regimes of their heat treatment that would ensure a specif ied level of operating properties require the development of scientifi cally substantiated approaches to the solution of this problem. The ef ficiency of fasteners and holders is determined by a combination of th eir mechanical properties. A change in the heat treatment regime affec ts each characteristic differently, which complicates experimental det ermination of optimum heat treatment regimes. In our opinion, a ration al approach to the solution of this problem is the creation of mathema tical models of the change in the properties of a steel as a function of the technological factors. Such models make it possible to optimize the technological parameters of treatment without conducting addition al experiments.
