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.

Novel Processing Techniques for γ-TiAl Alloys

, 2011
The processing of large or near-net shaped parts from g-TiAl alloys is extremely challenging. The forging of large-scale TiAl-parts is hampered by the unavailability of high-quality, chemical homogenous pre-material.
