β 21 S ( nominal composition Ti-15 Mo-3 Al-2.7 Nb-0.2Si ) titanium alloy is a metastable β-titanium alloy developed by Timet to serve the U. S. Air NASP space shuttle program for antioxidant and metal matrix composite materials. The alloy has excellent cold workability, deep hardenability, creep resistance, high oxidation resistance, and good corrosion resistance, and can be used to produce temperature-required aircraft structural parts or engine parts as well as hydraulic pipe fastener, sheet metal, etc. The alloy has already been used to manufacture wind guide of Boeing-777 engine compartment and other components. As a typical metastable β-titanium alloy, β 21S alloy may obtain ultrahigh tensile strength, that is, 1 300 MPa or above, and elongation no less than 6% through appropriate heat treatment. In order to fully understand and master the performance of β21 S titanium upon high-strength heat treatment process, we conducted a comprehensive performance test of titanium β 21S.
