淬火是金属合金热处理过程中一道非常重要的工序。通常是把需要处理的零件浸入能够蒸发的液体中(例如水、水溶液或矿物油)来完成淬火的。另一种可能的淬火方法是用液体喷洒零件,其优点是能够采用计算机控制,并可能使用直到目前为止尚未能使用的新型冷却剂。为了获得所需要的组织,合金必须进行通常包括一系列加热和冷却操作过程的热处理。对热处理方法的任何改进以及透彻了解如何才能获得特定的组织都要求进行许多领域的研究,而进行这些研究需要热传导、流体力学和固体力学以及自动化方面的知识。
Quenching is a very important process in the heat treatment of metal alloys. Quenching is usually accomplished by immersing the part to be treated in a liquid that can evaporate (such as water, an aqueous solution, or mineral oil). Another possible quenching method is to spray the part with a liquid, which has the advantage of being computer-controlled and possibly using a new type of coolant that has not been used until now. In order to obtain the desired microstructure, the alloy must be heat treated, usually involving a series of heating and cooling operations. Any improvements in heat treatment methods and a thorough understanding of how to get a particular tissue will require research in many areas that require knowledge of heat transfer, fluid dynamics and solid mechanics, and automation.
