加熱轉(zhuǎn)變奧氏體的形成奧氏體化——若溫度高于相變溫度鋼，在加熱和保溫階段，將發(fā)生室溫下的組織向A的轉(zhuǎn)變，稱為奧氏體化。奧氏體形成的四個(gè)步驟：1）奧氏體晶核的形成；A晶核通常在珠光體中F和Fe3C相界處產(chǎn)生。
1）整體熱處理（退火，正火，淬火，回火）；2）表面熱處理（火焰加熱表面淬火，感應(yīng)加熱表面淬火，激光加熱表面淬火等）；3）化學(xué)熱處理（滲碳，滲氮，滲其它元素等）。（2）根據(jù)熱處理在零件加工中的作用分1）預(yù)先熱處理（退火，正火）：為機(jī)械零件切削加工前的一個(gè)中間工序，以切削加工性能及為后續(xù)作組織。
