摘要：
Ribbons of an Mg-9.76 wt.%Sn alloy have been fabricated using rapid solidification technology. X-ray diffraction and transmission electron microscopy confirm that the rapidly solidified ribbons consist of alpha-Mg, beta-Mg2Sn and beta ''-Mg3Sn phases. The alpha-Mg grains are refined in the ribbons. The predominant fraction of the beta-Mg2Sn phase distributes at the grain boundaries of the alpha-Mg grains. The minor fraction of the beta-Mg2Sn phase reveals a spherical morphology with a typical grain size of 170 nm. The orientation relationship between the beta ''-Mg3Sn particles and alpha-Mg matrix is identified in the ribbons and an atomic structure model of the beta ''-Mg3Sn phase is proposed.
