摘要: 实验结果表明:以乙二酸水溶液为电解浸蚀液,可以在钼单晶体表面上显示位错的浸蚀斑。选{100}面为观察面,沿三叉亚晶界定出了浸蚀斑密度。观测结果证实了不对称倾侧晶界的Read-shockley公式,由此确定了沿亚晶界排列的浸蚀斑与柏格斯矢量为的刃型位错间的一一对应关系。

Abstract: Oxalic acid solutions are used for producing etching pits on the surfaces of molybdenum crystals grown from electron-beam floating zone melt. By taking {100} as observation plane, dislocation densities along traces of three intersecting subboundaries are measured and the Read-Shockley formula for asymetrical tilt boundaries has been verified. The one-to-one correspondance between etching pits along these subboundaries and edge dislocations with Burgers vector < (100) is demonstrated.
