Abstract
Beta-type alloys are the most versatile class of titanium alloys. They offer the highest strength to weight ratios and very attractive combinations of strength, toughness, and fatigue resistance inlarge cross sections [1]. The present study was made to obtain useful information for the design of ${\beta}$-type titanium alloys with high-strength properties by using the $DV-X{\alpha}$ method. Employing two calculated parameters, the bond order (Bo) and the d-orbital energy level (Md) of alloying elements in ${\beta}$-type titanium alloy was introduced and used for prediction of mechanical properties. Thus, high-strength titanium alloys were designed by calculating the Md and Bo values of the previous and present titanium alloys.
