HRTEM Investigation of Precipitates in Al-Zn-In-Mg-Ti-Ce Anode Alloy
The precipitates of Al-5Zn-0.02In-1Mg-0.05Ti-0.5Ce (wt %) anode alloy were studied by scanning electron microscopy, X-ray microanalysis, high resolution transmission electron microscopy and selected area electron diffraction analyses in the present work. The results show that the alloy mainly contains hexagonal structure MgZn2 and tetragonal structure Al2CeZn2 precipitates. From high resolution transmission electron microscopy and selected area electron diffraction, aluminium, Al2CeZn2 and MgZn2 phases have [0 1 -1] Al || [1 -10] Al2CeZn2 || [-1 1 0 1] MgZn2 orientation relation, and Al2CeZn2 and MgZn2 phases have the [0 2 -1] Al2CeZn2 || [0 1 -10] MgZn2 orientation relation.
