On the general outline of physical properties of amorphous-nanocrystalline Fe–Cr–Mn–N alloy powders prepared by mechanical alloying under nitrogen

This paper reviews last findings about physical properties of Fe–Cr–Mn–N powders synthesized by mechanical alloying under nitrogen. Their thermal, magnetic, indentation, and grain growth behaviors and nitrogen distribution in their amorphous-nanocrystalline structure are regarded as a function of milling time. Particularly, the role of nitrogen in the aforementioned phenomena is reviewed in detail.
