U-0.75 (0.5, 1.0) Ti alloy is an age-hardenable alloy and undergoes a martensitic transformation on quenching. The hardening sequence includes quenching from the gamma phase to maintain the Ti in solid solution. Because problems arise when the cooling rate is reduced in the center of parts (such as a penetrator rod), an attempt was made to find a third element to reduce the quenching rate sensitivity. Transitron elements, Fe, Y, and rare earths (misch metal) were tested as this third element. Misch metal gave an indication of reducing the alloy's quench-rate sensitivity in the Jominy test. 26 figures. (DLC)
