Revised Semiempirical Approach to Predict the Occurrence of Twinning in Titanium Alloys

[Image: see text] A revised semiempirical approach, considering the average values of the valence electron to atom ratio (e/a̅) and a difference in atomic radii of alloying element/s and the base element (Δr̅), is proposed to predict the twin formation in titanium alloys. The revised e/a̅ versus Δr̅...

description [Image: see text] A revised semiempirical approach, considering the average values of the valence electron to atom ratio (e/a̅) and a difference in atomic radii of alloying element/s and the base element (Δr̅), is proposed to predict the twin formation in titanium alloys. The revised e/a̅ versus Δr̅ diagram is plotted, considering the reported results of 90 titanium alloys fabricated using various processing methods. A new twin/slip boundary has been plotted and recommended based on the revised e/a̅ versus Δr̅ diagram. The conventional maximum limit reported for the twinning in titanium alloys is e/a̅ = 4.20; however, it has been found that twinning in titanium alloys is possible up to the e/a̅ of 4.30.
