The removal unit in processing is substantially decreasing along with the miniaturization of industrial products. The bulk material is no longer a continuous solid body from a microscopic viewpoint. It is, therefore, important to understand the behavior of each component/element in micro tribology. In this study, an indentation and scratching test was performed on an annealed material S25C carbon steel. The phenomenon of ferrite and pearlite in the microscopic region is clarified, while the results are also extended to interpret microscopic phenomenon.
