摘要：

We report a novel Zn-Mg-Dy phase, denoted as the tau-phase, whose structure is related to that of the Frank-Kasper type decagonal Zn-Mg-Dy phase, based on electron diffraction and high-resolution transmission electron microscopy studies. A plausible atomic model is proposed, which is constructed by two types of atomic clusters related to those in the Zn7Mg4 crystalline compound.
