【摘要】 用扫描电镜观察金属的脆性断口或微粒矿物时,将试样台进行适当的旋转和倾斜操作,可以直接观测晶面的夹角。因此,可以标定晶面指数和晶粒位向。本文对操作步骤予以阐述,对该方法的适用性及局限性亦加以讨论。更多还原

【Abstract】 A rotation-tilting technique in SEM is proposed. By means of this technique, one can directly measure the angle between crystal facets. this is usefal in the study of metallic bri ttle fracture surface or mineral crystallite. The principle and procedure of this operation are described, the application and limitation of this technique are discussed.更多还原
