Influence of the Reactor and Cyclotron Irradiation on Energy Transformation during Plastic Deformation of Metal Materials
SourceThe processes of energy dissipation and accumulation were studied during plastic deformation. In addition, the characteristics of strength and ductility were obtained for pure metals and structural materials pre-irradiated by neutrons or alternatively by alpha-particles. The temperature dependencies were obtained and analyzed for both strength and ductility characteristics and stored energy. It was found, that for the studied materials in their unirradiated and/or irradiated conditions, the stored energy increase correlates with the applied stress increase, i.e. Es∼σn, where n = 2 at early stages of deformation. Due to radiation effects the material, ability to accumulate mechanical energy decreases to a great extent with irradiating fluence increase. At the same time, heat release is increasing during deformation process.
