ball milling alloy

Ball milling is effective to smash the Cu4Zr4 and Zr8 alloys to fine particles, but cannot fracture the Cu8 alloy to particles, indicating an inherent high ductility and strength of the Cu8 alloy. Therefore, the macroscopic brittleness of the polycrystalline Cu8 alloy was mainly caused by the weak grain

This is mainly because of the formation of nanostructured disordered FeAl alloy in the sample prepared by ball milling meth-od. Apart from this the presence of Aluminium peak in case of sample prepared through Arc melting indicates the uneven distribution of Al into Iron matrix whereas, in Ball Milled sample, complete dissolution of Al into Fe lattice is observed.
