Abstract:

Additional forging of slugs by upsetting with a single 1750 ft-lb blow was conducted on both Mo0.5Ti and TZM in InFab and air. Maximum plasticity of as cast material in the cold work temperature region occurred at 2100 F and below. Minimum plasticity over the temperature range 1800 F to 4075 F occurred at 3200 F. Cold worked and partially recrystallized slugs machined from a TZM alloy extrusion exhibited consistent plasticity from 1900 to 2400 F. Plasticity improved with temperature above this point. At 3650 F, a hot worked structure with a hardness of 190 DPH resulted. Decreasing plasticity with hold time at temperature in excess of 5 min was indicated at 2650 F. Essentially no difference was found between 0 and a 5-min hold up to 3200 F. At 3650 F there was a considerable increase in upset with 5-min hold for Mo0.5Ti but not with TZM. Author
