摘要：

This paper assesses the possibility of synthesizing bulk nanostructured or ultrafine structured metallic materials by consolidation of powders using high strain powder compact forging. In the work, inter-particle boundaries were categorized into three types: Type I-fresh surface/fresh surface boundaries, Type II-fresh surface/oxide covered surface boundaries and Type III-oxide covered surface/oxide covered surface boundaries. The possibility of turning each of these types of inter-particle boundaries into grain boundaries or interphase boundaries without causing significant grain/particle growth through plastic deformation, and the amount of plastic deformation needed were discussed. The related experimental findings were also reviewed. It was concluded that by using high strain powder compact forging the possibility of producing bulk nanostructured or ultrafine structured metallic materials is very high.
