摘要：

In connection with an investigation of the mechanism of high-temperature embrittlement the neutron irradiation induced embrittlement of three Cr-steels and one Mo-steel was studied in the range of the ferrite-austenite transformation-temperature, which was different due to the chemical compositions. The specimens were irradiated at 50 °C up to a fluence of 5 × 1019 n/cm2 (thermal). The results of the tensile test clearly indicate that a high-temperature embrittlement of the Cr-steels only occurs at temperatures above the α-γ-transformation. The Mo-steel, which shows a tendency towards intergranular fracture in the unirradiated condition already embrittles below the α-γ-transformation. No influence of the transformation on the embrittlement could be observed. The results are discussed. © 1969.
