回火回火tempering将经过淬火的工件重新加热到低于下临界温度的适当温度，保温一段时间后在空气或水、油等介质中冷却的金属热处理。钢铁工件在淬火后具有以下特点：①得到了马氏体、贝氏体、残余奥氏体等不平衡（即不稳定）组织。②存在较大内应力。③力学性能不能满足要求。因此，钢铁工件淬火后一般都要经过回火。作用回火的作用在于：①提高组织稳定性，使工件在使用过程中不再发生组织转变，从而使工件几何尺寸和性能保持稳定。②消除内应力，以便改善工件的使用性能并稳定工件几何尺寸。③调整钢铁的力学性能以满足使用要求。回火之所以具有这些作用，是因为温度升高时，原子活动能力增强，钢铁中的铁、碳和其他合金元素的原子可以较快地进行扩散，实现原子的重新排列组合，从而使不稳定的不平衡组织逐步转变为稳定的平衡组织。内应力的消除还与温度升高时金属强度降低有关。一般钢铁回火时，硬度和强度下降，塑性提高。回火温度越高，这些力学性能的变化越大。有些合金元素含量较高的合金钢，在某一温度范围回火时，会析出一些颗粒细小的金属化合物，使强度和硬度上升。这种现象称为二次硬化。要求用途不同的工件应在不同温度下回火，以满足使用中的要求。①刀具、轴承、渗碳淬火零件、表面淬火零件通常在250℃以下进行低温回火。低温回火后硬度变化不大，内应力减小，韧性稍有提高。②弹簧在350～500℃下中温回火，可获得较高的弹性和必要的韧性。③中碳结构钢制作的零件通常在500～600℃进行高温回火，以获得适宜的强度与韧性的良好配合。淬火加高温回火的热处理工艺总称为调质。钢在300℃左右回火时，常使其脆性增大，这种现象称为第一类回火脆性。一般不应在这个温度区间回火。某些中碳合金结构钢在高温回火后，如果缓慢冷至室温，也易于变脆。这种现象称为第二类回火脆性。在钢中加入钼，或回火时在油或水中冷却，都可以防止第二类回火脆性。将第二类回火脆性的钢重新加热至原来的回火温度，便可以消除这种脆性。
