According to the Al-Zr phase diagram, the maximum equilibrium solubility of Zr in Al is ~0.25 wt% [21]. The absence of Zr-rich precipitates in the gas atomized powders of the alloy with 0.5 wt% Zr reflects the increase in the solubility originated by the high cooling rate involved ...
The phase diagram of the Al-Er-Zr ternary system at 773K has been experimentally investigated by means of x-ray powder diffraction (XRD), differential thermal analysis (DTA) and scanning electron microscopy (SEM) with energy dispersive analysis (EDX). The existence of 13 binary compounds, i....

In addition, according to the Al-Zr binary phase diagram, the maximum solid solubility of Zr in Al was only 0.07%. Thus, during the solidification of liquid Al-5Mg-0.12Zr alloy, element Zr was enriched in front of the solid-liquid interface and led to constitutional supercooling, which ...
