The composition, crystal structure and precipitation crystallography of a newly found precipitate are characterized by Cs-corrected scanning transmission electron microscopy. The composition of the plate-like precipitate could be expressed as MgxAl2-xGd (x = 0.38), and its crystal structure is the same as the face-centered cubic type Laves phases Mg2Gd and Al2Gd, with a lattice parameter of 7.92Å (space group No. 227,). The orientation relationship between the matrix and precipitate is found to be (0001)m//(111)p and [100]m//[10]p, and the habit plane is parallel to the (0001)m//(111)p plane. In addition, this preferred crystallography of phase transformation is well explained on the basis of the atomic matching at the interface.The composition, crystal structure and precipitation crystallography of a newfound MgxAl2-xGd precipitate are characterized by Cs-corrected scanning transmission electron microscopy.
