Swelling, strengthening and embrittlement of beryllium under neutron irradiation to a fluence of 1.72mult10 exp 21 n/cm exp 2 (E > =0.85 MeV) at a temperature of 330-350 deg C. The role of main structure factors

Nine modifications of sintered (distilled and technical) beryllium were irradiated, investigated and compared. The major changes as a result of irradiation were shown to be variation of density, an increase in strength properties and decrease in plasticity properties. An expression that links swelli...

Summary:Nine modifications of sintered (distilled and technical) beryllium were irradiated, investigated and compared. The major changes as a result of irradiation were shown to be variation of density, an increase in strength properties and decrease in plasticity properties. An expression that links swelling or additional sintering of the material with its initial porosity, total impurity content and mean grain size has been suggested.
