Effect of austenitizing temperature on divorced eutectoid transformation of GCr15 steel
The effects of holding temperature and holdmg time during the spheroidizing annealing on microstructure and mechanical properties of high-carbon chrome steel GCr15 were experimentally studied,especially the ripening process of carbides.The results showed that the spheroidization of carbides was accelerated by optimizing the spheroidizing annealing process.In the case of the same holding temperature,the amount of carbides increases first and then decrease with the increase of holding temperature.The best spheroidizing temperature was about 720℃.Under the conditions of various holding time,the size of carbides and the hardness decrease with the increase of holding time.
