Use of charged particle beams for research of mechanical behaviour of thermonuclear reactor first wall candidate - materials

Systematic analysis of radiation creep experiments at cyclic irradiation have been provided, in first. Peculiarities of radiation defects generation in metals at various charged particle bombardment are analyzed. Original method which connect radiation creep and stress relaxation is described. Stress relaxation in aluminum under 100 MeV carbon ions bombardment and Al-Mg-Sc alloy under 5 MeV electron bombardment have been investigated. Effects cyclic irradiation is obtained. It is show that radiation creep under cyclic irradiation may be described of “climb plus glide” mechanism.
