Abstract:

The effect of phase transformations on the mechanical properties including fracture toughness of the titanium alloy Ti-6Al-6V-2Sn has been investigated for various heat-treated conditions. Based upon a preliminary hardness survey of solution temperatures from 1300 to 1800 F, solution treatment temperatures of 1400, 1550, and 1700 F were selected for further aging heat treatments ranging from 700 to 1100 F for times up to 32 hours. X-ray and electron microscopic observations and elastic modulus determinations were employed and correlated the mechanical property data. A detailed discussion of the results and observations is contained in the paper. Author
