Abstract

A comparative study was carried out for an alloy of Al50(Ni75Mo25)50 processed by two different high energy ball mills. A SPEX and Simoloyer mill were used. The milled products were characterized using X-Ray Diffraction and Scanning Electron Microscopy. A different morphology and microstructural evolution were found with each mill used. It was evident that prolonged milling time induced the formation of two different intermetallic compounds (AlNi or AlMo3). Furthermore, the milling intensity had an important effect on its microstructural evolution and phase formation sequence.
