Abstract : An open die, pancake forging study was conducted to determine the interplay of beta processing variables (temperature, deformation, and cooling rate) in controlling the as-worked (wrought) microstructure of Ti 6Al-4V. Emphasis was placed on obtaining the finest wrought beta structure and/or finest recrystallized beta grain size. Both macrostructures and microstructures were prepared and observed optically. It was found that the finest wrought structure was obtained by increasing the amount of deformation at the higher temperature for either air cooling or water quenching. Recrystallization ensues if the material is held in the beta field immediately after forging. (Author)
