The dependence of microstructure, hardness and electrical resistivity on the purity of TiAl alloys with 50, 53 and 56 at.% Al was investigated by comparing materials prepared from high-purity metals by clean processing methods, to materials prepared from commercial metals. Grain size and resistivity were found to depend both on purity and on Al content, whereas hardness varied little with the overall purity, in the investigated range.
