Abstract
A wrought and heat treated titanium alloy part is disclosed having the composition, by w eight, Al 4.5 to 5.4%, Sn 1.8 to 2.5%, Zr 3.5 to 4.8%, Mo 2.0 to 4.5%, Cr 1.5 to 2.5%, Cr+V 1.5 to 4.5%, Fe 0.7 to 1.5%, O 0.07 to 0.13%, the remainder being Ti and impurities. The part is characterized by a fine and regular alpha-beta structure and essentially segregation free microstructures, and has the mechanical characteristics: Rm.gtoreq.1200 MPa, R.sub.p0.2 .gtoreq.1000 MPa, A%.gtoreq.5, K.sub.1c at 20.degree. C..gtoreq.45 MPa..sqroot.m, creep at 400.degree. C. under 600 MPa:0.5% in more than 200 hours.
