A new technique idea of γ-TiAl/Ti alloy composite sheet preparation was presented. Ti-43Al-9V-0.3Y/Ti-6Al-4V composite thin sheet with 3 mm thickness was produced by clad rolling technology at 1150 °C with 80 % total deformation amount. The thickness of Ti-43Al-9V-0.3Y alloy and Ti-6Al-4V alloy is about 2.3 mm and 0.7 mm in the composite sheet, respectively. The composite sheet after clad rolling has intact shape without stress cracking. Analyses show that the interface phases of the composite sheet are mainly composed of α2-Ti3Al. Tensile test reveals that, with increase of Ti-6Al-4V thickness, both the tensile strength and elongation are obviously increased at room temperature. When the thickness of the Ti-6Al-4V layer reaches up to 0.7 mm (the total thickness is 2 mm), the tensile strength and elongation of the composite sheet exceed 800 MPa and 4% at room temperature, respectively. And elongation of the composite sheet exceeds 25% at 700 ℃.
