Abstract

Mixed powders of aluminium and titanium (10 wt %) have been mechanically alloyed in an Attritor mill. A metastable solution of titanium in an aluminium matrix is obtained. Changes produced on shape and particle size, structure and microstructure, have been studied when milling time varies between 2 and 10 h. The final processing is carried out for a milling time of 10 h, with approximately 9 wt % of titanium dissolved in the matrix. Finally, a heat treatment is carried out at different temperatures, up to a maximum of 625 °C, which produces the precipitation of different phases such as different structures of Al₃Ti and Al₄C₃. The appearance of these second phases is characterized according to the selected heat treatment temperature.
