AbstractAbstract
[en] High temperature embrittlement by (n, α)-produced helium has been recognized as one of the life time controlling phenomena for first wall and blanket structural materials of future fusion devices. Especially the influence on fatigue properties is of great concern for the design of tokamak and ICFR components. Therefore, fatigue experiments on AISI 316 and 8206 steels (European and Japanese reference materials) were performed. Helium generation was simulated by preimplantation at a cyclotron. The fatigue tests were carried out in the reversed bending mode in high vacuum with 100 μm thick foil specimens containing up to 1500 appm helium. (orig./MM)
