Abstract:An algorithm and software for analyzing and optimizing the processes of austenization and formation of martensitic and bainitic structural zones in the hardened layer due to continuous serial heating and hardening with the use of sectioned power current inductors are developed. The suggested computer technology based on criteria of the fullness of occurrence of processes of homogeneous austenization and on thermokinetic diagrams of austenitic transformation makes it possible to compute the heating power, the velocity of motion of the inductor, the number of passes in heating, the number of sections in the inductor, their sizes and position, and the width of the cooling zone required for ensuring the specified thickness and structure in the hardened layer.
