Accelerated carbide spheroidisation of bearing steel by induction heating
Original language description
New type of thermal treatment for carbide spheroidisation was developed in COMTES FHT. Conventional heat treatment for carbide spheroidisation consists in long annealing at temperatures around temperature A1. Diffusion based process of pearlite shape transformation from lamellar to globular morphology takes usually several hours with subsequent cooling in furnace. The new heat treatment was performed using induction heating allowing rapid heating and thus rapid structure changes. Accelerated carbide spheroidisation principle is based on fast temperature cycling around transformation temperature A1. The purpose of this annealing process is to obtain globular carbides uniformly distributed in the matrix and to achieve overall softening in several minutes. The present paper explores the effect of the newly-designed thermal schedules on the cementite lamellae fragmentation, on the decrease in hardness in bearing steel grade 100CrMnSi6-4 and on processing times.
