Abstract (en)
The invention relates to an alpha + beta type titanium alloy bar consisting essentially of 4 to 5 % Al, 2.5 to 3.5 % V, 1.5 to 2.5 % Fe, 1.5 to 2.5 % Mo, by mass, and balance of Ti, and having 10 to 90 % of volume fraction of primary alpha phase, 10 mu m or less of average grain size of the primary alpha phase, and 4 or less of aspect ratio of the grain of the primary alpha phase on the cross sectional plane parallel in the rolling direction of the bar. The alpha + beta type titanium alloy bar has excellent ductility, fatigue characteristics and formability. <IMAGE>
