Equilibri di fase nelle regioni terminali del sistema Neodimio-Oro
Differential thermo-analysis, chemical analysis, metallographic and X-ray examinations were used for studying Nd–Au alloys. The comparison between results obtained performing thermoanalysis by heating pre-annealed samples or by cooling them from the melt shows that, very often, slow rates of formation delay the equilibration of the solid phases. Following invariant equilibria were observed: Eutectic: Liq ⇄ Au + AuNd (800° ± 5) Peritectic: Liq + AuNd ⇄ AuNd (840° ± 5) Peritectic: Liq + AuNd...
Misura di calori di formazione nel sistema Platino-Stagno
The general trend of the exothermic heat of formation of the Pt-Sn alloys has been outlined by using a “direct calorimeter”. Typical values of the are the following: , , Kcal/g.at.
