Web1 de mai. de 2012 · The Cr threshold concentration is more precisely estimated to be 7.2 at.% at 325 °C and 8.3 at.% at 400 °C [3] while Bergener et al. [4] reported a solubility limit of Cr in a-Fe–Cr of 8.8 +/− 0.2 at.%, ignoring a possible asymmetry of the miscibility gap. WebThe phase diagrams of binary alloys are known to vary with pressure. Within the framework of solution-type models, the variation is controlled by the pressure dependence of the elemental end members, which is relatively well known, and that of the excess interaction, which is unknown.
