Abstract
ABSTRACTTexture analyses have been conducted on gamma titanium aluminide (γ-TiAI) strips produced using the recently developed plasma melt overflow process. The results indicated that <101] deformation textures persisted in the γ-phase while <0002>, <1010> and <1020> texture components were all observed in the α2-phase. After annealing at 1065°C/48 hrs., the γ-phase textures did not change while the α2-phase changed from a basal to a <1010> texture. It is suggested that the texture development in direct cast γ strips produced using this technique are a direct result of lattice rotations and residual stresses caused by nonuniform cooling.
