The effects of milling power and milling time on phase evolution during high-energy ball milling, were investigated for the Al(50)Si(30)Fe(15)Ni(5) alloy. Elemental powders were milled in a SPEX 8000 apparatus and the resulting powders were characterised by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). Partially amorphous powders, together with the (Al,Si)(7)Ni(3) intermetallic compound, were obtained in early stages of milling. Silicon remained unreacted throughout long milling times, with particle size diminishing down to nanometric levels. Long milling times resulted in a single amorphous phase, though highly contaminated by the milling tools. Milling time and milling power showed a compensatory effect on the nature of phases obtained.
