摘要：

The primary phases, reaction sequences, and temperatures during solidification of Al-rich Al-Li-Cu alloys were studied using optical microscopy, electron probe microanalysis (EPMA), X-ray diffraction (XRD), scanning electron microscopy (SEM), differential thermal analysis (DTA), and chemical analysis. Boron nitride (BN), which was found to be inert to these alloys, was used as the container material. A new liquidus projection is proposed. The temperature and composition of the ternary eutectic, L = alpha + T(B) + T1, were determined to be 522-degrees-C at Al-8.0 at. pct Li-17.9 at. pct Cu.
