[Display omitted] •During annealing, the growth characteristics of Al-Er intermetallic compounds are accord with layer-terraced growth.•In Al-Er system, AlEr grows by consuming Er component, the growth of Al3Er proceeds by swallowing AlEr.•The pre-exponential factor and activation energy of the Al3E...
