Steels having less than the eutectoid amount of carbon (less than 0.77%) are known as hypo-eutectoid steels.
含碳量少于共析体(低于0.77%)的钢称为亚共析钢。

含碳量少于共析体(低于0.77%)的钢称为亚共析钢。
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.
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。
