Jump-type changing of deformed stress in aluminium and nickel at high-energi carbon ion beam cycling

An experimental method of studying mechanical properties of metals during charged particle irradiation is described. The method for performing short-time mechanical and relaxation tests in the course of irradiation with charged particles consists of the following systems: a) beam diagnostics and monitoring; b) loading; c) force measurements; d) sample temperature sustainment and measurements. The experiments were carried out on the U-200 and U-300 cyclotrons of the JINR Laboratory of nuclear reactions at accelerated carbon ion energies of 108 and 84 MeV. The first results obtained for aluminium and nickel irradiated with carbon ions are given
