Grain boundary structure and mechanical properties of the TiAl intermetallic compound

摘要

An investigation of the TiAl intermetallic compound mechanical properties has been undertaken in the temperature interval of 20-900 °C and at 1025 °C. Its properties has been found to be considerably dependent on the structure and properties of grain boundaries. The absorption properties of grain boundaries and mechanical behaviour of the intermetallic material are shown to be interrelated.
