卸去外加应力，对其进行回复退火，合金发生逆转变，即从马氏体转变为奥氏体。

The reverse transformation of martensite to austenite takes place when the alloys are annealed after the external stress is unloaded.

不锈钢的光亮热处理有马氏体不锈钢(如400系列)光亮淬火、奥氏体不锈钢(如300系列)光亮退火。

Bright heat treatment of stainless steel are martensitic stainless steel (such as the 400 series), bright quenching, austenitic stainless steel (such as the 300 series), bright annealed.
