摘要

The phase abundances of 16 alloys with various contents of Sn, Co, Al, and Fe additives were studied by X-ray diffraction analysis. Due to relative small percentages, the relative abundances of these minor phases were obtained through smoothing, curve fitting, and area integration and correlated qualitatively to the amount of additives in the alloys. In the Laves phases, Sn, Co, and Fe with more outer-shell electrons than that of the host alloy promote CI 5 phase. Al, with less outer-shell electrons, on the other hand, promotes C14 phase. In the AB phases, Sn promotes the formation of ZrNi phase and suppresses the formation of TiNi phase.
