摘要：

A systematic study of the influence of structure on the mechanical properties of a brittle TiAl intermetallic compound was undertaken in the temperature interval from 20 to 900-degrees-C. The area and structure of grain boundaries were shown to play an important role in the mechanical behaviour of the compound under study: the growing area of random boundaries provides for the enhancement of the intermetallic compound plasticity. The kinetics of the interaction of lattice dislocations with the grain boundaries were found to be related to the mechanical properties of the intermetallic compound.
