Research Abstract

Surface damage behavior due to helium ion irradiation under stress loading in nano-structured tungsten alloy was evaluated in order to estimate the applicability to plasma facing material. The current nano-structured tungsten alloy showed almost the same surface damage resistance as the commercial pure tungsten under low energy helium ion irradiation around 1000C when the irradiation fluence exceeded the peculiar value (1 x 10^<22>He/m^2in this study). Moreover, the effect of stress loading during helium ion irradiation was not clear above the peculiar fluence.
