Materialverhalten unter Bestrahlung

Abstract

There is a lack of really comprehensive presentations of the behaviour of materials under irradiation, which are qualified for an introduction of this field of knowledge. Therefore this report gives access to the contents of an appropriate lecture of the author at the Karlsruhe university which thus becomes available to a larger circle of readers. First the different kinds of radiation are presented with regard to their effect on materials, and also the groups of materials to be considered under technical aspects. A separate chapter is devoted to the particularities of the irradiation behaviour of polymer and glass materials. But the main importance is subsequently given to the presentation of the irradiation effects in crystalline materials with the following items: Atom displacement rate under neutron irradiation, effect of point defects and formation of defect aggregates, volume change, change of electric, thermal and mechanical properties of ceramics, graphitic and metallic matrials. Finally the significance of atom transmutation under neutron irradiation is treated, especially with regard to radioactivation and gas bubble formation.
