X-ray and Nuclear Magnetic Resonance Study of Mechanical Alloying of Cu 59 -Zr 41 Mixed Powders

63 Cu nuclear magnetic resonance investigation, together with x-ray diffraction, of the mixed Cu 59 -Zr 41 powders during mechanical alloying is reported. The results show that the s -electron density of states at Fermi surface is reduced and polarization effects exist during alloying. It is concluded that amorphization or more generally true alloying reaction has taken place by ball-milling through the strong interaction between copper and zirconium powders in the mixtures within atomic scale.
