The strength differential in some titanium alloys

Dec 01, 1973 · Such distortions are found in titan- ium alloys due to interstitial impurities which cause large expansions along the c-axis of the titanium lattice (9). This could account for the SD in the Ti-5% A1 21% Sn alloy in the various structural conditions and the vanadium-bearing alloy in the martensitic condition (318A).
