Plastic deformation characteristic properties of irradiated austenite corrosion-resistant steels in the temperature range 20...450 degree C

The main signs of the low-temperature radiation embrittlement of structural materials are described; the effect of the crystalline lattice type, of the test temperature and of the irradiation dose,of deformation rate, of the microalloying by REth, of the metal purity on the low temperature radiation embrittlement is considered. The influence of the neutron irradiation dose on the plastic deformation of steels and alloys in the temperature range of low-temperature radiation embrittlement is studied. The diagram of the ultimate strength and the yield point, of the elongation change of austenite structural materials in dependence on the irradiation dose,on the dislocation density and on the nickel content is proposed. The methods of the increase of the austenite steels and alloys resistance to the low temperature radiation embrittlement are considered
