In article number 1900183, Guang Yang and co‐workers examine microstructure characteristics of α phase in Ti‐40Al‐8Nb‐0.5B alloys after deformation in the β and (β + α) phase regions. The phase constitutes of the sample deformed above β transus are β, α phases and borides (TiB with B27 structure). The α phase with a lath‐like shape precipitates from the β phase obeying the Burgers orientation relationships (BORs), the equiaxed α phase nucleates on the borides and does not respect the BORs with the β phase.
