3D imaging of precipitates in al Aluminium-Copper-Lithium Alloy
Results of STEM HAADF electron tomography of an aluminium-copper-lithium alloy. a) Surface visualisation of a tomographic reconstruction, where different colours represent different secondary phases. These phases are primarily two families T1 and θ'. A colour key is shown above. b) Zoom in, and rotate, of boxed area in a) showing unknown phases and clear evidence of intersecting plates (boxed areas).
