The precipitation behavior of Cu-rich precipitates in Cu-implanted Fe films has been studied using transmission electron microscopy and electron diffraction. The results show that micro-twins which lie parallel to a (112)bcc plane as well as spherical copper particles with diameter less than 5 nm are observed in the as-implanted specimens. Upon thermal ageing, the precipitation in the Cu-implanted Fe films proceeds more rapidly than it does in the corresponding Fe-Cu alloys, and large copper precipitates are observed to grow near the micro-twins.
