ABSTRACT:
A near-beta titanium alloy having higher strength than ‘Ti-17’ is provided, while suppressing cost increase. Such a near-&bgr; titanium alloy consists of, in weight percent, 0.5-7% of V, 0.5-2.5% of Fe, 0.5-5% of Mo, 0.5-5% of Cr, 3-7% of Al, and the balance of Ti and impurities. When the weight % of V content is expressed as XV, the weight % of Fe content is expressed as XFe, the weight % of Mo content is expressed as XMo, and the weight % of Cr content is expressed as XCr; the value of XV+2.95XFe+1.5 XMo+1.65XCris 9-17%.
