Abstract : A comprehensive evaluation was conducted to (a) develop a heat-treat cycle which will improve the fracture toughness of Ti-6Al-6V-2Sn without markedly affecting its other properties and (b) verify that the 'recrystallization anneal' cycle developed for Ti-6Al-4V rolled plate will also improve the fracture toughness of Ti-6-4 die forgings. The program included tensile, fracture toughness, stress-corrosion, and fatigue tests.
