Abstrakt: A series of aluminium samples have been implanted at room temperature with a low dose of argon ions. The development of argon bubbles from the initially sub-microscopic argon clusters has been studied by annealing the samples to a series of temperatures up to 0.97Tm. The argon content of selected volumes of each sample has been determined by X-ray analysis in the transmission electron microscope (TEM). This result has then been compared with that calculated from measurements of bubble sizes taken from TEM micrographs of the visible bubble population in the same volume of the sample. The results indicate that sub-microscopic argon clusters may survive after annealing to temperatures as high as 500°C. Evidence is also found for the trapping of argon at the air formed surface oxide-metal interfaces.
