Abstract

A tetrahedral MgYNi₄ phase is prepared by melting method, and then formation mechanism associated with three-dimensional (3D) morphology is proposed. The tetrahedral MgYNi₄ crystal is enclosed by four closed-packed {111} planes, arising from the 4-fold rotoinversion symmetry of MgYNi₄ structure. The secondary arms grow along <110> directions between four primary trunks. The {111} lamellas grow from secondary arms to face center and shape up a tetrahedral skeleton with hollows. As {111} lamellas grow, the skeleton can be filled up and the perfect tetrahedral MgYNi₄ is formed.
