Precipitation behavior during aging at 873 K in a Cu–4.5 wt%Co alloy was investigated by means of electron microscopy. The sets of satellites along 〈100〉 directions flanking the matrix reflections were observed in the electron diffraction patterns of samples in the early stage of aging. With the progress of aging, the satellite reflections moved towards the matrix spots. The arrays of precipitates aligning along 〈100〉 directions were locally observed in images.
