Abstract: By optical metallography, XRD, DTA, SEM, TEM, HREM and computersimulation the microstructure of Ni3Al-Mo alloy prepared by spray atomization deposition isexamined and studied in detail. The microstructure of preform consists of uniform equiaxialgrains, with the size range of 10-40 μm, there also exists microporosity. Except the mainphases of matrix alloy, γ' and γ, there exist minor Ni2Mo, Ni3Mo phases found to be withinthe γ network. A new phase enriched in Ni in the γ phase has been identified to have fee structure with lattice constant a=1 .09nm, and space group Fm3m.
