摘要:
The phase relationships in the Al-Zr-La ternary system at 773 K have been investigated for the first time mainly by means of X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) equipped with energy dispersive analysis (EDX). The existence of the Al4La5 and AlLa2 binary compounds has been confirmed in this ternary system. The isothermal section consists of 18 single-phase regions, 33 two-phase regions and 16 three-phase regions. No ternary compound was observed in this work. (C) 2010 Elsevier B.V. All rights reserved.
