【Abstract】

<正>Size effect at submicron scales is a crucially important issue on plasticity of materials.There are two main mechanisms that govern the plastic behavior at the submicron scales as the dimensions variation of the compressed pillars.The first is dislocation starvation induced by the annihilation of dislocations from the free surfaces.The second is forest dislocation hardening induced by
