Ni-Nb-Zr metastable phases formation, a thermodynamic and chemical approach.

Gibbs� free energy of formation is considered a good guidance in order to describe or predict the phases�formation within standard state; however, many materials are produced out their equilibrium conditions, and consequently, metastable phases formed. There no universal knowledge related formation; therefore, this paper presents considerations elucidate some understanding about two found rapid quenched alloy from Ni-Nb-Zr system during solidification process. The analyzed alloy, namely Ni61.6Nb33.1Zr5.3 (at.%) was previously synthesized characterized previous works. hypotheses presented here consider energies among which compete nucleate, stability crystalline at nanoscale atomic pair preferences nucleation. may produce improve promising technological materials.
