Calculation and Analysis of Diffusion Kinetics of Alloying Elements in Bearing Steel

Abstract:

In order to detect the diffusion law of alloying elements in 0.95c-1.45cr-0.35mn-0.25si bearing steel during annealing process,the database of tcfe7 and mobfe of dictra software were used to calculate the diffusion kinetics. The results show that c atoms diffuse rapidly in single fcc phase field and at last uniform,temperature and holding time have no significant influence on them;cr,si,and mn has the same diffusion mechanism,the initial solidifying field has lower solute than the subsequent,and has slight change after solidification. The improvement of segregation factor (cr) at 1300°C for 5h is better than at 1050°C, 1200°C for 10h.
