Abstract

The secondary phases in quasicrystal-reinforced Mg-Zn-Gd alloys are investigated by transmission electron microscopy. The orientation relationships between the dendritic I-phase and the Mg matrix are identified to be [11 2¯ 0]_Mg ∥[2-fold]_I-phase and (0001)_Mg ∥(5-fold)_I-phase. We also find that the dendritic I-phase is brittle along 2-fold, 5-fold, and 3-fold atomic planes during hot extrusion. Moreover, new orientation relations [1¯ 101]_Mg ∥[mirror 2-fold]_I-phase and (0 1¯ 11)_Mg ∥(5-fold)_I-phase are found between nanoscale I-phase and Mg matrix. The findings have implications for our understanding of excellent mechanical properties of the I-phase-strengthened Mg alloys.
