C. Dimitrov et al., INFLUENCE OF PURITY LEVEL ON THE MICROSTRUCTURE AND SOME PROPERTIES OF GAMMA-TI-AL INTERMETALLICS, Journal de physique. IV, 3(C7), 1993, pp. 481-484
The dependence of microstructure, hardness and electrical resistivity
on the purity of TiAl alloys with 50, 53 and 56 at.% Al was investigat
ed by comparing materials prepared from high-purity metals by clean pr
ocessing methods, to materials prepared from commercial metals. Grain
size and resistivity were found to depend both on purity and on Al con
tent, whereas hardness varied little with the overall purity, in the i
nvestigated range.
