Abstract:

The paper describes work, done in 1957-58, in the course of the development of the high-temperature HT Ti alloy currently termed BT9VT9. 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 kgmmsuperscript 2 and a 50-hr creep limit with 0.2 percent residual strain of not less than 30 kgmmsuperscript 2, and which would manifest satisfactory thermal stability and plasticity at room temperature.
