There are many scrapped products or raw materials caused by the quenchcracks of metal workpieces.
金属材料工件因淬火裂纹造成产品或原材料报废的实例很多。

QuenchCracks: Cracks formed in a steel part during or after quench, resulting from high stresses in cooling; could be caused by water in the quench oil.
淬火裂纹:裂纹在钢材的淬火或淬火后形成,由于冷却时的高应力所造成;也有可能是在淬火油中的水所导致。

The major reason of the formation of quenchcracks is the contamination of oxygen in the early processing or unsuitable quench cooling rate during heat treatment.
