几十年来，热处理人员都知道液体淬火的缺点:开裂、变形、流动不均匀等等。虽然淬火是零件最后的热处理过程之一，但它是最不为人所知的过程之一，尽管这是因为除了将零件浸入油中并提供搅拌之外，该做什么；没什么大不了的，对吧？现在不是了。

Heat treaters have for decades known the disadvantages of liquid quenching: cracking, distortion, flow nonuniformity, and many more. Although quenching is one of the last heat treatment processes a part is subjected to, it is one of the least understood, albeit because what's to do but immerse the part in oil, and provide agitation; no big deal, right? Well, not anymore.
