WebFe-Pt intermetallic nanocrystals exhibit good chemical stability and unique magnetic and catalytic properties. However, there are still some discrepancies with regard to the order-disorder transitions of Fe-Pt phases, and experimental works reported for the phase equilibria of Fe-Pt alloys at low temperatures are scarce. Therefore, in this work, the … WebNov 9, 2006 · The results of the investigation of the phase relations in the Fe–Pt–Nd ternary system at 900. °C are given in the present work.. 2.. ExperimentalThe solid-state phase equilibria of Fe–Pt–Nd system at 900. °C were investigated with 80 samples.. All the alloys were made by arc melting on a water-cooled copper hearth under an argon atmosphere.

WebPd-Pt: this binary phase diagram is similar to that of the Pt-Ir system; however, Pd diffuses much better in Pt. The miscibility gap contributes to the hardening of such alloys. Au-Pt: the miscibility gap in Au-Pt systems is the reason for the good hardening behavior of these alloys (a typical dental casting alloy is DA2 in Table 1.5 and in ... WebJan 19, 2012 · The Fe-Pt phase diagram is reviewed by Okamoto as shown in Figure 1 based on the diagrams published by Okamoto, Osaka et al., and Nose et al. They have shown different composition ranges of the phases and confusion still exists.
