The effect of Ta and W additions on microstructure mechanical properties tilt-cast Ti-45Al-5Nb-2C (at.%) alloy was investigated. Three alloys with nominal composition Ti-45Al-5Nb-2C-2X (in at.%), where X is or W, were prepared by vacuum induction melting in graphite crucibles followed tilt casting into moulds. the consists α2(Ti3Al) + γ(TiAl) lamellar grains, single γ phase, (Ti,Nb,X)2AlC parti...
