Abstract
The results are given of an investigation of low-cycle fatigue of the austenite class 03Kh20N45M4BCh chromium alloy, realized in its application to the selection of materials for the manufacture of structural elements of the thermonuclear reactor discharge chamber. The loading regime consists of alternating elastoplastic strain by twisting a thin-walled tubular specimen with holdings of 200-sec duration. Radiation tests were carried out in a materials science channel of the WR-M (water-cooled and water-moderated) reactor of the Institute of Nuclear Research at the Academy of Sciences of the Ukrainian SSR in a flux of fast neutrons 4.5 ' 1013 neutron · cm2 · sec. The effect of neutron irradiation on strain and strength properties of the investigated alloy are evaluated. Comparison is made of the data on the effect of irradiation on the low-cycle fatigue of some steels.
