Tensile Properties and Deformation Mechanisms in Two-Phase Titanium Aluminide Sheet Material

The mechanical properties of two-phase TiAl sheets with different compositions and microstructures were investigated over the temperature range 25–1000 °C. The microprocesses of plasticity were characterized by electron microscope observations. Particular emphasis has been paid to the mechanisms governing the deformation behavior at elevated temperatures which are relevant for the fabrication and engineering applications of structural components.
