DEVELOPMENT OF HIGH-TEMPERATURE TITANIUM ALLOY VT9,

Abstract

The paper describes work, done in 1957-58, in the course of the development of the high-temperature (HT) Ti alloy currently termed BT9(VT9). The target requirements for the new alloy specified the development of a Ti alloy for forging billets and stamping blanks which at 500 degrees centigrade would have a 100-hr stress-rupture strength of not less than 55 kg/mm(superscript 2) and a 50-hr creep limit (with 0.2 percent residual strain) of not less than 30 kg/mm(superscript 2), and which would manifest satisfactory thermal stability and plasticity at room temperature.
