Transmission electron microscopy analysis of the crystallography of precipitates in Mg–Sn alloys aged at high temperatures

The crystallographic orientation relationships of precipitated β-Mg₂Sn particles in Mg–9.76 wt% Sn alloy aged at 573 K for 5 h were investigated by advanced transmission electron microscopy (TEM). Models of the interface of precipitated β-Mg₂Sn and the α-Mg matrix were constructed via high-resolution TEM and atomic resolution high-angle annular dark-field scanning TEM.
