Process for preparing 1mm diameter transparent films for TEM from neutron-irradiated austenitic materials and the apparatus for carrying out the process

摘要

A method of preparing 1 mm diameter transparent foils from metallic materials for analysis by transmission electron microscope, especially for research into neutrons of irradiated austenitic steels consists of a first step where samples are prepared by cutting from tensile samples in a shielded hot or semi chamber, ground to 200 μm thick and in the second phase to 60 μm in glove boxes, the last step is electrolytic polishing using a 1 mm diameter modified film holder.;Also described is the apparatus for carrying out the method comprising a holder for cutting small dimension irradiated tensile samples, a mechanical punch for punching a disc and a modified holder for electrolytically cleaned film.
