On the α–α′ miscibility gap of fe–cr alloys
Web28 de mar. de 2016 · The separation of a Cr-enriched nanometer-scale α′ phase can induce the embrittlement of Fe-Cr alloys at high temperature, and the separation kinetics of the α′ phase determines its spatial morphology. The quantitative kinetics of the α′ phase formed by spinodal decomposition was studied in a Fe-42 at.% Cr alloy by phase-field simulation at … Webmost symmetrical α-α′ miscibility gap and yield a zero solubility limit of Cr in Fe at low temperature. How-ever, first principles calculations by Hennion13 in 1983, confirmed a few years later by a neutron study of short range order (SRO)14,15 have shown that Fe-Cr alloys dis-play an ordering tendency for low chromium contents.
