    Sammanfattning : When thin foil specimens of copper-iron alloys containing metastable fcc - iron are bombarded with argon ions the precipitates are induced to transform martensitically to bcc iron. Using stereo microscopy techniques it was established that (1) transformation is limited to those particles near the surfaces of the specimen, (2) particles on the non-irradiated surface can transform even although the irradiation damage does not extend this deeply.
