austemper

1.Replacin oil quenching process with austemper process, bend intension of part and stability in using are advanced.

具体零件,应等温淬火工艺代替油冷淬火工艺,提高了零件的屈服强度,使零件在使过程中的稳定性得到提高。

2.The results showed that with the increase of austempering temperature, the bainite morpholoy changes from needled lower bainite to feathered upper bainite then to ear of wheat like then flakiness.

结果表明：随着等温温度的升高，贝体的形态由状下贝→毛状上贝体→麦穗状→片状；
