critical hardening temperature
基本解釋
- 臨界淬硬溫度
英漢例句
- The lower heat-treating temperature of the case results from the fact that hypereutectoid steels are normally austenitized for hardening just above the lower critical point.
由于恰好高于低臨界溫度通常使過(guò)共析鋼奧氏體化而硬化，所以對(duì)外層采用較低的熱處理溫度。 - Hardening . This is the process of heating to a temperature above the critical range , and cooling rapidly enough through the critical range to appreciably harden the steel .
淬火，該工藝是加熱工件到臨界溫度以上，然后以足夠快的速度進(jìn)行冷卻通過(guò)臨界溫度區(qū)域以使工件明顯硬化。
chenyanli1975.blog.163.com - Tempering . This is the process of heating quenched and hardened steels and alloys to some temperature below the lower critical temperature to reduce internal stress setup in hardening.
這是把加熱急速冷卻到臨界溫度之下的某一溫度，使鋼和合金硬化的工藝，用來(lái)減小硬化中產(chǎn)生的內(nèi)應(yīng)力。
