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.

Web30 de jan. de 2024 · Abstract. The status of miscibility gap alloys (MGA), which have demonstrated excellent characteristics for thermal storage applications over a wide range of temperatures, is reviewed. MGA remain macroscopically solid whilst delivering latent heat from embedded metal particles supplemented by the sensible heat of the whole material. Web1 de mar. de 2024 · In this study, four FeCrAl model alloys with 10–18 at.% Cr and 5.8–9.3 at.% Al were neutron-irradiated to nominal damage doses up to 7.0 displacements per atom at a target temperature of 320 °C.

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. map of grand bahama hotels
