On the Bauschinger effect in TiAl alloys [PDF]
Acta Materialia, 2016 Abstract The Bauschinger effect has been investigated at room temperature on a multiphase titanium aluminide alloy based on γ(TiAl). The effect of strain reversal was assessed by comparing uni-directional tensile tests with those performed on specimens made from pre-compressed material.
