The property changes caused by heat treatment in Ti6% Al-4% V are described, and the effect of a high alloy addition was investigated. The tensile strength increases on quenching at 800 deg C and attains a value of 120 kg/mm/sup 2/ with good expansion and contraction at quenching temperatures between 900 and 950 deg C. The yield point and yield point ratio pass through a minimum at 800 to 850 deg C. By annealing at 500 deg C the yield point is increased, and the tensile strength is also increased but to a lesser degree. A maximum tensile strength can only be obtained with small sample dimensions since the resulting cooling velocity is very great. With higher beta consitituents the hardness of the alloy can be increased. A too high content of beta stabilizing elements causes a decrease of the ductility, and the stability of these alloys is lower. The properties of the alloy at higher temperatures are better than in other commercial titanium alloys. A molybdenum addition leads to a great improvement of the heat strength tn the tempered state.
