| titleOfInvention | Method of heat treatment of titanium alloy product |
| abstract | An article formed of an alpha-beta titanium-base alloy, preferably an alloy having more than about 3.5 weight percent molybdenum, for example a gas turbine compressor blade (20) having a nominal composition, in weight percent, of about 4 percent aluminum, about 4 percent molybdenum, about 2 percent tin, about 0.5 percent silicon, balance titanium and impurities, is processed to form a martensitic structure therein. The processing, which typically involves forging or weld repairing, includes the steps of first heating the article to a first-heating temperature of greater than about 1600 DEG F, and thereafter first cooling the article to a temperature of less than about 800 DEG F. The article is thereafter second heated to a second-heating temperature of from about 1275 DEG F to about 1375 DEG F for a time of from about 1 to about 7 hours, and thereafter second cooled to a temperature of less than about 800 DEG F at a second cooling rate that does not exceed about 15 DEG F per second. <IMAGE> |
