Abstract:
     In this invention a pulse magnetic field of 30 cycle-300 kilocycle pulse frequency and 1500-85000 ampere/m is used. This technique will accelerate chemical heat treatment process and shorten production cycle for steel annealing, quenching and tempering. It can be used to replace the cold treatment of high precision parts.
