Optimization and controlling of the microstructure and mechanical properties of high-Nb TiAl alloy by extrusion temperature

Hot extrusion is an effective route to tailor the microstructure and mechanical performance of TiAl intermetallic alloys. In the present work, a Ti-45Al-8Nb-0.2W-0.1B alloy was multi-pass extruded at five temperatures spanning the (α + γ) two-phase region to the α single-phase re...
