Effect of hot-deformation on the microstructure of the Ti-Al-Nb-W-B alloy

► Large ingot of the TiAlNbWB alloy has larger grain size as compared to the small drop-casting specimen. ► More residual β phase can be observed in the large ingot. ► Thermal mechanical processing and related heat-treatments can refine the grain size and reduce the amount of β phase in the large ingot alloy.
