Precipitate extraction by an electrolytic separation technique and analytical thermodynamic calculations as a function of the solubilization temperature and chemical composition were employed. In the first procedure of preferential electrolytic phase dissolution, samples were submitted to a solubilization treatment, followed by quenching.

The microstructures were characterized via scanning electron microscopy (SEM/EDS) and transmission electron microscopy (TEM/EDX) techniques. The results revealed by the Z-phase (Cr2Nb2N2) precipitation potential (Ks) that the precipitates acted as a softening inhibitor agent and retarded the grain growth at lower solubilization temperature conditions (Ts < 1100 °C). The considerable amount of fine precipitates were mainly formed due to the nucleation and coalescence of Cr/NbN in the matrix. On the other hand, larger precipitates nucleated and coalesced above 1200 °C, and had their volume fraction reduced at this condition.Kayron Lima SilvaSamuel Filgueiras RodriguesGlaucia Maria Evangelista MacedoBruno Leonardy Sousa LopesClodualdo Aranas, Jr.Fulvio SicilianoGedeon Silva ReisEden Santos SilvaElsevierarticleOrthopedic implantsAustenitic stainless steelGrain refinementPrecipitationSolubility productMining engineering.
