文摘

A novel TiAl alloy with excellent tensile properties was manufactured by extrusion. The as-extruded alloy demonstrated a good combination of high strength and ductility. The dislocation structures of B2 phase grains were investigated in detail. The B2 phase was beneficial to the room-temperature ductility of the present alloy.
