Structural changes of TiAl deformed by high-strain torsion — •Guang-hui Cao, Guang-hui Cao, Werner Skrotzki, Carl-georg Oertel, Werner Skrotzki, and Carl-georg Oertel — Institut fur Strukturphysik, Technische Universitat Dresden, 01062 Dresden, Germany
High-temperature extruded two-phase TiAl/Ti3Al intermetallics have been deformed by torsion and their microstructures have been investigated by transmission electron microscopy. The microstructural changes observed consist of break-down of the lamellar structure and deformation induced precipitation of TiAl3 and Ti2Al. The study is expected to be helpful for understanding the relationship between the microstructure and mechanical properties which can be changed drastically by high-strain torsion.
