本文报告了对称型堆垛层错是Ni_3Al多晶体形变缺陷的重要组成部分。这种对称型堆垛层错的产生,是由分布在相邻{111}晶面上的位错偶在切应力的作用下进行移动、分解和合并销毁的结果。
TEM analysis and computer simulation of the symmetrical superlattice intrinsic stacking faults (SISFs) in slightly deformed polycrystalline Ni_3Al at room temperature are presented. The symmetrical SISFs are important components of the crystal defects in deformed Ni_3Al alloys; the formation mechanism of the symmetrical SISF can be resulted from the reorientation, dissociation and annihilation of a dipole on {111} plane under applied shear stress.
