Evolution of microstructure and texture of a near α titanium alloy during forging bar into disk

Ti6242S alloy bar with equiaxed microstructure and random textures was selected to investigate evolution of microstructure and texture during the process of forging bar into disk by isothermal constant speed hot compression test. Experimental investigation shows that αp grains experienced bend, rotation under prismatic slip system action and further separated into refined grains by dynamic recovery or dynamic recrystallization with the...
