研究了 GCr15 钢的温变形对球化退火的影响。结果表明:珠光体温变形显著加快了碳化物球化过程。随变形量、变形速度的增加及变形温度的降低,球化速度增加,变形量是影响球化速度最显著的参数。珠光体的温变形促进了在790℃加热、保温过程中渗碳体的溶解和未溶渗碳体粒子的圆整过程。还对温变形试样快速球化退火工艺进行了试验。 The effect of temperature deformation of GCr15 steel on spheroidizing annealing was studied. The results show that the deformation of pearlite significantly accelerates the spheroidization of carbide. With the amount of deformation, the increase of deformation speed and the decrease of deformation temperature, the speed of nodularity increases and the amount of deformation is the most significant parameter that affects the speed of nodularity. The temperature deformation of pearlite promotes the rounding process of the dissolved and undissolved cementite particles during heating and holding at 790 ℃. A rapid spheroidizing annealing process was also tested on the warm deformed specimens.
