THE FRACTURE TOUGHNESS OF 3 Ti ALLOYS R. Chait and T.S. DeSisto

strength variation of several high strength Ti alloys using a quotNavahoquot rib and web forging. To reveal the influence of micro structure in more detail, recent studies at AMMRC have focused on the heavy section mechanical properties of 3 Ti alloys: Ti6Al4V, Ti6Al6V2Sn and Ti8Mo8V2Fe3Al. Materials and Test Procedure

Absorption and diffusion of oxygen in the Ti 3 Al alloy .

The absorption and diffusion of oxygen in the Ti 3 Al alloy are studied by the projector augmented wave within the density functional theory. The highest absorption energies are shown to correspond to the sites in the octahedra formed by six titanium atoms, and the presence of aluminum in the nearest neighbors leads to a substantial decrease in the binding energy of oxygen in the alloy by .

ever, may promote formation of Ti 3Al, which can degrade the alloys resistance to stress corrosion. A duplex anneal is used to obtain maximum stability in the nearalpha alloys Ti8Al1Mo1V and Ti6Al2Sn4Zr2Mo. First step is a solution anneal at a temperature high in the alphabeta range, usually 25 to 55C
