摘要：

An investigation was undertaken to ascertain the extension of the B2 phase fields from AlNi and AlRu in the Al-Ni-Ru ternary system. The samples were are-melted, annealed at 1500 or 1600 degrees C, and examined using optical microscopy, scanning electron microscopy, and X-ray diffraction. Apparent two-phase samples were deduced as being cored because of the indistinct boundary between the phases, and the variation of the component compositions with alloy composition. The presence of an isostructural compound, AlNixRu1-x was indicated by the continuous variation from AlRu to AlNi in lattice parameter and a smooth trend microhardness with a maximum. It is unlikely that both of these trends would have been observed in a system with a two-phase region. (C) 1998 Elsevier Science S.A.
