一、hardening翻译

hardening机械行业中翻译为:淬火,使金属硬化

water quenching 机械行业中翻译为:水淬

oil quenching机械行业中翻译为:油淬

国内论文多把淬火翻译为“hardening”,其实翻译为“quenching”更贴切一些。

二、术语介绍

2.1淬火定义

机械专业英语:hardening(淬火)

机械专业英语:hardening(淬火)

淬火,金属和玻璃的一种热处理工艺。钢的淬火是将钢加热到临界温度Ac3(亚共析钢)或Ac1(过共析钢)以上温度,保温一段时间,使之全部或部分奥氏体1化,然后以大于临界冷却速度的冷速快冷到Ms以下(或Ms附近等温)进行马氏体(或贝氏体)转变的热处理工艺。通常也将铝合金、铜合金、钛合金、钢化玻璃等材料的固溶处理或带有快速冷却过程的热处理工艺称为淬火。

2.2淬火目的
淬火的目的是使过冷奥氏体进行马氏体或贝氏体转变,得到马氏体或贝氏体组织,然后配合以不同温度的回火,以大幅提高钢的强度、硬度、耐磨性、疲劳强度以及韧性等,从而满足各种机械零件和工具的不同使用要求。也可以通过淬火满足某些特种钢材的铁磁性、耐蚀性等特殊的物理、化学性能。
