与此类似，渗碳层厚度越大，特别是对于渗碳层厚度不一的渗碳用钢，淬火时更易产生翘曲。

Sim? ilarly, an increase in case depth, particularly uneven case depth in case hardening steels, increases warpage on quenching.

当这种钢冷却时，就像图2.1的z - z线所示，除了初步的或预共析状态用渗碳体取代铁素体外，其余类似亚共析钢的情况。

When such steel cools, as shown in zz 'of Fig. 2.1 the process is similar to the hypo-eutectoid case, except that the primary or pro-eutectoid phase is now cementite instead of ferrite.
