...Generally, the influence of microstructure on mechanical properties of γ-TiAl based alloys can be summarized as follows: coarse-grained “fully lamellar” (FL) and “nearly lamellar” (NL) microstructures exhibit relatively high fracture toughness and creep resistance, but poor tensile ductility and strength especially at room temperature [1-4]....
