Notes:
Dual two-phase intermetallic alloys composed of geometrically close packed (GCP)structures of Ni3Al(L12) and Ni3V(D022) containing Nb were investigated in terms of themicrostructural evolution during low temperature annealing (aging) and the related mechanicalproperties. The eutectoid region, i.e. the prior Al phase (Ni solid solution) is composed of thelamellar-like structure consisting of Ni3Al(L12) and Ni3V(D022) phases. The lamellar-like structuretended to align along 〈001〉 direction and on {001} plane in the prior A1 phase (or the L12 phase).In a wide range of temperature, the dual two-phase intermetallic alloys showed high yield andtensile strength, and also reasonable tensile ductility, accompanied with ductile fracture mode
