高速钢的冷处理,虽然早在三十年代就有人提出过,但始终未在工业中广泛应用,由于当时提出目的是使高速钢能在零度以下迅速冷却,引起残余奥氏体转变成马氏体,以便使它代替多次回火工艺,用以提高效率。通常的冷处理工艺是将淬火后的高速钢件立即冷处理,以避免残余奥氏体停留而稳定化。然而由于没有能简化热处理工艺过程,和所做的许多寿命试验也未发现有何提高,因而它就没有在高速钢上应用,只用于稳定尺寸。减少轴承钢、量具钢,热处理发生的残余奥氏体等方面。
Although the cold-working of high-speed steels was proposed as early as the 1930s, it has not been widely used in industry because the aim was to rapidly cool high-speed steels below zero, causing the retained austenite to transform into martensite , In order to make it instead of multiple tempering process, to improve efficiency. The usual cold process is the quenched high-speed steel immediately after cold treatment, to avoid the retention of retained austenite and stability. However, since there has been no improvement in the heat treatment process and many life tests done, it has not been applied to high-speed steels and only used to stabilize the dimensions. Reduce the bearing steel, gauge steel, retained austenite and other aspects of heat treatment.
