Abstract
Two new metastable crystalline (MX) phases were formed in the Ni-Nb system by solid state reaction (SSR) of multilayered films at medium temperatures. The first one was the Ni-rich hcp phase and the second one was the Nb-rich fcc-I MX phase. A Gibbs free energy diagram of the system was constructed by calculation of the free energy curves of the alloy phases, and the MX ph ase formation is correlated with the constructed diagram. The growth kineti cs of the MX phases is also discussed.
