On irradiating IIIX 15 steel with electrons hardening occurred in the surface layer. Closer to the surface the layer consists of martensite and residual austenite. At a certain depth excess carbides were observed in addition to the structural components. On heating up to 100-200 deg C martensite disintegration occurred only in the layer containing excess carbides; on heating up to 300--500 deg C -it went on throughout the entire irradiated layer. Disintegration of the residual austenite was observed on attaining 500 deg C, the disintegration products having a higher hardness than the residual austenite. Tempering at 600--700 deg C led to the formation in the irradiated layer of a disperse ferrito-carbide mixture of the troostite type. Thus, transformations in irradiated steel during tempering are shifted by 100--200 deg C toward the higher temperatures as compared with the same steel hardened in the conventional way. (auth)
