Phase relationships in the Al-rich region of the Al-Y-Zr system
TLDR
In this article, the phase equilibria in the Al-rich region of the ternary Al-Cu-Er system at 673 K were obtained, and the microstructures of as-cast alloys in this region were also investigated.Abstract:
The Al-rich region of the ternary Al–Cu–Er system is investigated using the method of X-ray diffraction, scanning electron microscopy with energy dispersive X-ray spectroscopy. Phase equilibria in the Al-rich region of the Al–Cu–Er system at 673 K have been obtained, and the microstructures of as-cast alloys in the Al-rich region are also investigated. One ternary phase 1-Al8Cu4Er with a composition of 59.4–60.4 at.% Al, 32.2–33.8 at.% Cu, and 6.4–7.7 at.% Er is observed in both as-cast and annealed alloys. At 673 K, the binary Al3Er phase dissolves about 3.51 at.% Cu. The calculated solidification paths (based on the CALPHAD method) of as-cast alloys are in agreement with the experimental results. © 2010 Elsevier B.V. All rights reserved.read more
