【摘要】 用俄歇电子谱仪对经过一定量的高温拉伸预变形试样以及未变形试样进行检测,结果表明:微量元素磷在高温拉伸过程中在晶界上有明显的动态偏聚行为。文章指出,高温变形时晶界与晶内变形程度的差异是导致磷在晶界上动态偏聚的驱动力。更多还原

【Abstract】 Predeformed and non-deformed specimens have been tested by Auger Microscopy.It can be seen clearly that trace element phosphorus segregate into grain boundary in hot tensile process.The paper proposes that the difference of deformation between grain and grain boundary caused by hot deformation is driving force for dynamic segregation.更多还原
