Such a long, fierce debate not only clarified the mechanism of quenchinghardening, but also improved our knowledge of the structure and properties of steels.
这场长达四十年的激烈争论不但阐明了钢的淬火原理,对钢的结构与性能的深入了解也是有益的。

Bearing parts in the process of hardening cooling by internal stress due to the formation of quenching cracks crack said.
轴承零件在淬火冷却过程中因内应力所形成的裂纹称淬火裂纹。
