Supplemental experiments on the Ce-Ge system
In the literature reported Ce-Ge phase diagram, the sharp change of the liquidus near the non-stoichiometric compound (CeGe) looks very unusual, leading to the motivation for the experimental measurements of the present work.The as-cast solidified microstructures of the Ce-Ge alloys between 40-60 at.% Ge are measured by XRD, SEM and EPMA in order to verify some of the invariant reactions of the Ce-Ge system.The experiments show that the compound (CeGe) melts congruently;the compound Ce5Ge4 is formed by the invariant peritectic reaction L+Ce5Ge3→CesGe4 and the microstructures of two eutectic reactions L→CesGe4+(CeGe) and L→(CeGe)+(βCeGe1.7) are observed.According to the present investigation, some phase equilibrium relations of the Ce-Ge phase diagram are modified.
