Numerical Modelling of Kinking in Lamellar γ-TiAl Based Alloys

Processing of titanium aluminides often starts with the break‐down of the coarse‐grained lamellar microstructure of the ingot. The lamellar colonies consist of alternating layers of γ‐TiAl and α2‐Ti3Al. The goal of this study is to investigate which local effects are responsible for the observed glo...

Zusammenfassung:Processing of titanium aluminides often starts with the break‐down of the coarse‐grained lamellar microstructure of the ingot. The lamellar colonies consist of alternating layers of γ‐TiAl and α2‐Ti3Al. The goal of this study is to investigate which local effects are responsible for the observed global softening of the material.
