Summary

The temperature dependent mechanical properties of the intermetallic TiAl(Cr,Mo,Si) alloys are strongly influenced by the microstructure, which is controlled by the processing parameters for the manufacturing of semi-finished products or components, and by minor modifications of the alloy composition. Comprehensive investigations on these alloys in various treatment conditions exhibit excellent physical and mechanical properties for applications as lightweight components in automotive and jet engines. TiAl base alloys are specifically suited for rotating and oscillating engine parts under high thermal and mechanical load, because of their low density, high specific mechanical properties and excellent oxidation resistance up to 700°C.
