Abstract
The results on the tolerance of several construction materials (D16T alloy, Zr, ЭИ-847, 12Х18Н9Т steels) and polycrystаlline SiC to blistering and flecking after irradiation with 500 keV He+ ions and following annealing have been high-lighted. Samples of stainless steels, zirconium, D16T alloy and silicon carbide were irradiated with helium ions in the range from 1016 to 3 · 1018 ion/cm2. Immediately after irradiation and annealing under temperatures from 300 to 750 °C, the optical microscopy was used to study the structure of surface layers. Temperature and fluence ranges of tolerance to blistering and flecking were determined for all examined materials. Primary types of material structure distortions were reviewed.
