摘要
Plastic strain was evaluated as a function of stress from data of the amplitude-dependent internal friction in polycrystalline Cu alloys. The solute elements were restricted within IVb group and the concentration was fixed at 0.3% in order to examine the dependence of flow stress on the size misfit between solute and solvent atoms. Results indicate that the size effect of solute atoms on the flow stress in the microplastic strain range is more remarkable than that in the macroscopic strain range.
