An obvious improvement on morphology, dis-tribution, amount and size of primary Ni_3Al(γ') intermetallic compound was approached bysuch alloying elements as Hf, Ti, Zr, but no more by Nb, W, Ta. The formation of ductileγ'-γ-γ' boudary in the alloys with refined primary γ'-phase may eliminate the weakened na-ture of brittle γ'-γ' boundary, and reduce the size of primary γ'-phase to tens of μm. thus, theductility of the alloys, especially at intermediate temperature may be markedly improved. Inaddition, an alloy free from Cr is still significantly ductile, only its structure refined. Theavailability of Cr to improving the intermediate temperature ductility seems to be due to thechange of amount and distribution of γ-phase.
