a, b Scanning electron microscopy (SEM) image showing the coarse equiaxed and columnar grains. c Schematic illustration showing the typical microstructure of the columnar grains with discontinuous Cu-rich precipitates. d Transmission electron microscopy (TEM) micrographs revealing discontinuous Cu-rich precipitates with periodic arrangements. e TEM micrographs showing dislocations distributed along the cellular and grain boundaries. f TEM image and corresponding energy-dispersive X-ray spectroscopy (EDS) mapping analysis showing the discontinuous Cu-rich precipitates.
