摘要：

Intermetallic compounds based on γ-TiAl are investigated to measure truly grain-size dependent mechanical properties which are unaffected by any processing flaws. The coverage of a wide grain size range is analyzed to ensure that the results may be tied to the data available for materials with conventional grain sizes. The results are evaluated in terms of the underlying deformation mechanisms.
