| 沉淀硬化不锈钢 Precipitation hardening stainless steel 沉淀硬化不锈钢锻件热处理包括三个过程：固熔处理、调整处理和时效处理。 The heat treatment of precipitation hardening stainless steel forgings includes three processes: solid melting treatment, adjustment treatment and aging treatment. 固熔处理：处理工艺为1000〜1030℃, lh,空冷。获得的组织为奥氏体加少量铁素体。 Solid melting treatment: the treatment process is 1000 ~ 1030 ℃, LH, air cooling. The microstructure obtained is austenite plus a small amount of ferrite. 调整处理：调整处理的目的是获得一定数量的马氏体，从而使钢得到强化。 Adjustment treatment: the purpose of adjustment treatment is to obtain a certain amount of martensite, so as to strengthen the steel. 时效处理：它是沉淀硬化不锈钢强化的另一途径。当时效温度高于400℃时，会从马氏体中析出金属间化合物，呈高度弥散分布，起沉淀硬化作用。一般在500℃时效，可获得高的硬度和强度。 Aging treatment: it is another way to strengthen precipitation hardening stainless steel. When the aging temperature is higher than 400 ℃, intermetallic compounds will precipitate from martensite, which are highly dispersed and play the role of precipitation hardening. Generally, aging at 500 ℃ can obtain high hardness and strength. |
