Influence of cooling rates on microstructure and tensile properties of a heat treated Ti2AlNb-based alloy

In the present study, a two-phase Ti2AlNb-based alloy with a nominal composition of Ti–22Al–25Nb (at%) comprising the dominant O + B2/β phase was explored. The microstructural evolution and tensile properties are studied by applying different heat treatment methods of water-cooling (WC, 140 °C/s) an...
