摘要：
Investigation of the influence of irradiation on the critical opening of the crack (COC) is performed on flat rectangular specimens with an edge crack for three-point bending tests which are fabricated from rolled steel 12KhGNMF. The radiation stability of this steel was estimated by results of tensile and shock bending tests. The influence of a different specimen irradiation temperature on the value of the critical crack opening was estimated during the tests. Specimens that were irradiated at the maximal (280°C) and minimal (240°C) temperatures were tested at identical temperatures. The data obtained showed that the difference in irradiation temperature in the 240-280°C range does not influence the resistance to brittle fracture for the steel 12KhGNMF.
