研究了08Mn2Si钢不同工艺处理后双相组织的形态及冷拔中组织与性能的变化,结果得到:950℃预淬火后再经临界区加热淬火时可以得到细小均匀的纤维状双相组枳,这种组织在冷拔中转变为很细的平行于拔丝方向的纤维状组织,且具有最好的强度和韧性。
The microstructure and properties of the duplex microstructure of 08Mn2Si steel after different treatments were studied. The results showed that the fine and uniform fibrous biphasic group Poncirus trifoliate orange could be obtained when pre-quenched at 950 ℃ and then quenched by the critical zone. This type of structure is transformed into a fine fibrous structure parallel to the direction of the strand during cold drawing and has the best strength and toughness.
