Mechanical alloying: a critical review

WEBOn milling the Fe 42 Al 28 Zr 10 B 20 powder mix for 20 h, amorphization had occurred, as evidenced by the presence of a broad diffuse peak centered at the angular position corresponding to the (110) Fe peak. On further milling (say, for 50 h), however, this diffuse peak started becoming sharp, and additional lowintensity peaks started appearing.
