Martensite transition in rapidly solidified Ti3Al-2Nb alloy

Abstract

The microstructure of rapidly solidified Ti3Al-2Nb alloy consists of an ordered orthorhombic α″0 phase. In the foil samples for transmission electron microscopy prepared by chemical thinning, the α″0 → β0 transformation took place due to the charging of hydrogen during thinning. The β0 → α″0 transition in the rapidly solidified alloy can be explained by a shape deformation mechanism, and the β0/α″0 interface (habit) plane is near to {334}β 0. The orientation relationships between the β0 and α″0 phases are \([\overline {1}\overline{1}0 ]{\beta _0}||{[001]_{\alpha _0^"}}\), and \((\overline {1}\overline{1}0 ){\beta _0} \wedge {(010)_{\alpha _0^"}} = (001){\beta _0} \wedge {(100)_{\alpha _0^"}} = 4.6^\circ\).
