Abstract
Abstract Dislocation structures in the γ-phase grains of Ti-45 at.% Al-10 at.% Nb specimens have been characterized after tensile tests at room temperature. In addition to ordinary dislocations with b = ½ ⟨110], a certain density of superdislocations and faulted dipoles were observed, which are rarely present in the conventional two-phase TiAl-based alloys of normal impurity. This difference was attributed to the solution of high Nb in the γ phase, which may increase the critical resoved shear stress for ⟨110] ordinary slip.
