Abstract : A production heat of Ti-7Al-2.5Mo in 1- and 2-inch plate thickness was evaluated. Mechanical properties were found to be uniform throughout the plates. Heat treatment studies showed that the 0.2 percent offset yield strength could be increased from 109 to 127 ksi while still maintaining adequate toughness. Mechanical properties in the heat-treated condition are reported. The Ti-Al-Mo family of alloys are strong candidates in the Titanium Hull Program, and additional work on this system is currently under way. (Author)
