Abstract

An aircraft flight data recorder housing (12) comprising a titanium alloy having a nominal composition of 10 weight percent vanadium, 2 weight percent iron, and 3 weight percent aluminum with the balance being titanium and, within limitations, certain trace elements. The alloy is preferably forged into a recorder housing (12) by a two-step isothermal forging process. Working during the first step occurs above the beta transus, while working during the second step occurs near, but below, the beta transus. It is preferred that about 70 to 90 percent of the work introduced into the housing (12) during the isothermal forging be introduced during the second working step. Subsequent heat treatment procedures combined with the above processing result in a fine grained recrystallized microstructure having discontinuous grain boundary alpha which surprisingly provide the alloy with very high penetration resistance.
