In metal microforming process, some material parameters, such as crystal microstructure, surface roughness etc. are the same as ones in macro scale material forming process, but its macro geometrical dimensions, such as foil thickness, wire diameter and indentation depth, are very small, in finally, the metal plastic forming behaviours are changed. The properties of metal material are different from macro scale forming and related with the macro geometrical dimensions, which is referred to as size effect. The conventional metal forming technology and theory in macro scale cannot be applied directly to metal plastic microforming through scale down the specimen and tooling size due to the lack of the material length scale in their constitutive models. In order to study on the size effects in microforming process, the strain gradient plasticity theory is developed, in which the conventional strain hardening and the strain gradient hardening are included together and the material intrinsic length is present in the constitutive relation. In present dissertation, the plastic stran gradient theories are studied to explain the size effects in metal microforming.
