测量了三种含磷量的Fe-P合金(0.007,0.06,0.09wt一%P)经70%冷变形后,在200-700℃真空退火过程中显微硬度值及应力一应变曲线随退火温度的变化,分析不同磷含量及其偏聚状态对Fe-P合金力学性能的影响,结果表明:磷原子“气团”对位错运动的钉扎作用类似C,N等原子的作用,使含磷合金出现类似碳钢的屈服现象,再次证明了回复状态下磷原子偏聚于位错线上
In recent years we systematically studied the action of P in cold rolled Fe-P alloys and discovered that P segregated preferentially along dislocation line and formed non-equilibrium structure, and also noticed that the non-equilibrium structure closely
