the shape and microstructure of defects in the surface of cvd diamond films were observed and analysed by sem technique. the defects includ twin crystal and hole.
用sem方法观察分析了cvd金刚石薄膜表面的缺陷形貌和结构,直观的两种缺陷为孪晶和孔洞。
in this paper the morphology of the ferrite twin deformation, the conditions of a thick twin crystal formation, and the various factors to decide the quantity of twins produced are analyzed.
用扫描电镜观察铁素体形变孪晶的形态,对厚片孪晶的形成条件及决定孪晶数量的各种因素进行分析。
at the time of deformation reached 40%, the appearance of the crystal changed greatly: the size refined, boundary turned clear, second phase disappeared and twin crystal structure appeared.
