Abstract:

Results are presented of tests to determine the consistency of commercial Ti-4Al-3Mo-1V 3 sources, the design strengths, the forming limits, the effect of processing on the material properties, and the resistance welding characteristics. The suppliers will provide material with a minimum ultimate strength of 180,000 psi and 155,000 psi yield strength after aging at 925 F for 12 hr. Ti-4Al-3Mo-1V alloy is subject to the Bauchinger Effect, and tensile strains developed by forming operations will cause a reduction in the compressive strength. Forming limits for manufacturing operations are based on sheets reworked by the Scotch Brite process to minimize grind marks.
