| 摘 要： | 轴类零件磨削时显微组织中的残余奥氏体因受磨削热的影响必将发生分解,并逐渐转变为马氏体,引起工件表面体积膨胀,导致组织应力产生,进而促进裂纹的形成。因此,工件内部残余奥氏体量较高时,易产生磨削裂纹。

| Abstract: | The retained austenite in microscopic structure when grinding shaft-like category parts will resolute because of the influence of the grinding heat,and gradually be transferred into mastenite,which will cause the expansion of the surface volume and lead to the production of structure stress,thus promoting the formation of cracks.Therefore,if the retained austenite is higher in the inner of the parts,great cracks will be easily found. |
