Many of the metallic materials used for industry is polycrystalline and their deformation behavior is microscopically heterogeneous. Then, it is important to study the microscopic deformation behavior of inhomogeneous material. In order to clarify the deformation behavior of inhomogeneous material, it is necessary to study the distribution of stress or strain, the microscopic surface shape, the influence of the geometry of constituents and the relation between local microscopic deformation and the global deformation behavior of the material. The aim of the present study is to clarify by experiments and analysis various features of microscopic plastic deformation.Observation with the laser scanning microscope as well as the scanning probe microscope was performed. The measured pattern was analyzed statistically, with the help of image processing technique. The local material characteristic was also measured with the ultra-micro hardness tester. The effect of orientation of grains was also measured with the electron back scattering equipment attached to the scanning electron microscope. The surface roughness was measured three-dimensionally and the effect of grain size was studied.

许多用于工业的金属材料是多晶的，它们的变形行为在微观上是不均匀的。因此，研究非均匀材料的微观变形行为具有重要意义。为了阐明非均匀材料的变形行为，需要研究应力或应变的分布、微观表面形状、成分几何形状的影响以及材料局部微观变形与整体变形行为之间的关系。本研究的目的是通过实验阐明并分析微观塑性变形的各种特征。使用激光扫描显微镜和扫描探针显微镜进行观察。借助图像处理技术对测量的图案进行统计分析。还用超显微硬度计测量了局部材料特性。还用扫描电子显微镜附带的电子背散射设备测量了晶粒取向的影响。三维测量表面粗糙度并研究晶粒尺寸的影响。
