HIGH-STRENGTH ALPHA-BETA TITANIUM ALLOY

摘要

An alpha-beta titanium alloy comprises Al at a concentration of from about 4.7 wt.% to about 6.0 wt.%; V at a concentration of from about 6.5 wt.% to about 8.0 wt.%; Si at a concentration of from about 0.1 5 wt.% to about 0.6 wt.%; Fe at a concentration of up to about 0.3 wt.%; O at a concentration of from about 0.15 wt.% to about 0.23 wt.%; and Ti and incidental impurities as a balance. The alpha-beta titanium alloy has an Al/V ratio of from about 0.65 to about 0.8, where the Al/V ratio is defined as the ratio of the concentration of Al to the concentration of V in the alloy, with each concentration being in weight percent (wt.%).
