Description

The phase equilibria of the Al-Er-V ternary system at 773 K has been investigated over the whole concentration range mainly by powder X-ray diffraction (XRD), scanning electron microscope (SEM) and optical microscopy (OM). This isothermal section consists of 14 single-phase regions, 26 two-phase regions, and 13 three-phase regions. There are 10 binary compounds, i.e. Al3Er, Al2Er, AlEr, Al2Er3, AlEr2, Al10V, Al45V7, Al23V4, Al3V and Al8V5 confirmed in the Al-Er-V system. The ternary compound Al43Er6V4 is confirmed and its lattice parameter is calculated and refined. The solid solubility of V in Al2Er3, AlEr and Al2Er are determined to be about 1-2 at.%, and the solubility of Al in V is 39 at.% at 773 K.
