At present, the demand to the improvement in the characteristic of steel material is expanded in the various directions with development of industrial technology, and investigation of the improvement is performed. We focus on precipitation hardening in strengthening mechanism of steel materials. In this study, we simulate an influence of copper precipitates on motion of an edge dislocation using Molecular Dynamics (MD) method in the iron-copper model alloys. In this paper, we compare the motion of the dislocation between copper precipitates of 3nm and 5nm, and discuss their difference.
