摘要：
The phase diagram for the Al-Cr system has been experimentally revised. The main features of the diagram in the literature have been confirmed. The gamma (Al11Cr2) phase has not been found in as-cast samples, heat-treated samples or samples subjected to differential thermal analysis. A diffusion couple treated at 650-degrees-C has not shown this phase either. The reaction involving the aluminium phase has been found to be of a eutectic nature. A new version of the Al-Cr phase diagram is proposed, taking account of these findings and literature data.
