淬火钢

The heat treatment method integrating isothermal annealing,quench hot and double tempering was made on the cold-work die steel XW-42 for its strengthening and toughening .

采用等温退火+高温淬火+二次回火工艺对冷作模具钢XW-42进行强韧化处理，提高了模具强度、塑性及韧性，此工艺应用于某型号表尺座的成形，模具使用寿命由原来的2400件提高到7300件，极大地降低了生产成本。

We heat it up beyond the critical temperature, and then quench it in water or some other liquid.

其方法是，把钢加热到临界温度以上，然后将其在水中或其他某种液体中淬火。

Low temperature properties of weld ; resistance measurement ; deep cooling treatment ; disperse educt ; brittle fracture at low temperature
