该法是利用预淬所得的马氏体对贝氏体的催化作用,来缩短贝氏体等温转变所需时间。因而该法适用于某些合金工具钢下贝氏体等温转变需要较长时间的场合。在等温转变过程中,预淬得到的马氏体进行了回火。在进行下贝氏体等温转变之前,先在中温区进行一次(或二次)分级冷却的工艺。该种工艺可减少热应力及组织应力,工件变形开裂倾向性小,同时还能保持强度、塑性的良好配合,适合于高合金钢(如高速钢等)复杂形状工具的热处理。此外,尚有液氮淬火法,即将工件直接淬入-196℃的液态氮中。因为液氮的汽化潜热较小,仅为水的十一分之一,工件淬入液氮后立即被气体包围,没有普通淬火介质冷却的三个阶段,因而变形、开裂较少,冷速比水大五倍。液氮淬火可使马氏体转变相当完全。

含碳量ωc为1%左右,含铬量ωcr为0.5%-1.65%。轴承钢又分为高碳铬轴承钢、无铬轴承钢、渗碳轴承钢、不锈轴承钢、中高温轴承钢及防磁轴承钢六大类。高碳铬轴承钢GCr15是世界上生产量轴承钢,含碳Wc为1%左右,含铬量Wcr为1.5%左右,从1901年诞生至今100多年来,主要成分基本没有改变,随着科学技术的进步,研究工作任在继续,产品质量不断提高,占世界轴承钢生产总量的80%以上。以至于轴承钢如果没有特殊的说明,那就是指GCr15。我国已生产高碳铬不锈轴承钢,主要钢号有9Cr18;渗碳轴承钢,主要钢号有G20CrMo;铬轴承钢,主要钢号有GCr15。轴承钢的物理性能主要以检查显微组织、脱碳层、非金属夹杂物、低倍组织为主。老化是指高聚物在长期使用和存放过程中,由于受各种因素的作用,性能随时间不断恶化,逐渐丧失使用价值的过程。其主要表现:橡胶变脆,龟裂或变软,发粘;塑料是退色,失去光泽和开裂。这些现象是不可逆的,老化是高聚物的一个主要缺点。轴承钢中的化学成分主要是碳、铬、硅、锰、镍、钼、钒等。除了渗碳钢外,一般轴承钢的含碳量在0.95—1.15%,属于过共析成分。这样在淬火和低温回火后能得到高的硬度、高的接触疲劳强度和耐磨性。为了形成足够的碳化物以增加耐磨性,含碳量不能太低,但是过高的含碳量会增加碳化物的不均匀性并且会形成网状碳化物使力学性能降低。铬是轴承钢的主要化学成分,铬能够提高淬透性,减少过热倾向,提高低温回火稳定性。
