| 摘 要： | 对两种不同原始组织的渗碳轴承钢G20CrNi2MoA试样分别进行正火、完全退火试验；对正常组织的G20CrNi2MoA钢试样通过不同的温度进行等温退火试验,观察组织变化.组织分析表明:正火可以消除带状组织；完全退火使得带状组织更加严重；等温退火温度越高带状越严重,当温度高于650℃时带状组织较明显.

| Abstract: | The normalizing and fully annealing tests were performed on the two samples of carburized bearing steel G20CrNi2MoA,which has two kinds of original structures;the isothermal annealing test has been done on the sample with normal structure,it was observed and shown that band structure can be eliminated by normalizing,while fully annealing makes the band structure worse,and the higher the isothermal annealing temperature is,the worse the banded structure is,which happens more obviously when the temperature is above 650 ℃. |
