Regulation of Ta element on the B2+γ like pearlitic microstructure and mechanical properties of Ti-46Al-2Cr-0.3Si alloy

The β/B2 phase is recognized to impair the room temperature plasticity of TiAl alloys. To address this problem, a novel B2+γ like pearlitic microstructure (LPM) has been proposed to enhance performance. In this work, Ti-46Al-2Cr-0.3Si- x Ta ( x = 0, 0.5, 1, 2, and 4 at.%) alloys...
