Modification of microstructure of 100CrMn6 steel by accelerated carbide spheroidisation process

Popis výsledku v původním jazyce

Processing of high-carbon chromium steels often includes an annealing stage, at which initial lamellar pearlite should be transformed into ferrite with globular carbides. The purpose of such treatment is to enhance machinability of the material or to condition the microstructure for subsequent hardening. Carbide spheroidising occurs through diffusion, which is a long-term and energy-demanding process. The holding times, sometimes up to tens of hours make soft annealing one of the most expensive heat treatment processes. The new process was newly designed at the company COMTES FHT shortens carbide spheroidising several times and therefore delivers considerable time and cost savings. The high-carbon chromium steels are not fit for further working unlesssoft-annealed. The purpose of this annealing process is to obtain globular carbides uniformly distributed in the matrix and to achieve overall softening. The present paper explores the effect of the newly-designed thermal schedules on the
