Modification of non metallic materials under the influence of the radiation and thermal retrogradation of these modifications; Modification de materiaux non metalliques sous l'influence des rayonnements et retrogradation thermique de ces modifications

Abstract

The action of the radiation on solids constitute an extremely vast domain of study, which the CEA hardly begins. There is not a very long time, indeed, that we have relatively intense fluxes (6.10{sup 12} thermal neutrons by cm{sup 2}.s{sup -} {sup 1} in the center of the reactor core of Saclay). Materials submitted to radiations, were followed by the evolution of a certain number of physical properties. The study of thermal retrogradation, at moderate temperature, of the modifications provoked by the irradiation were also followed. We will limit, in this report, to expose our experiences on graphite and lithium fluoride. (M.B.) [French] L'action des rayonnements sur les solides constitue un domaine extremement vaste dont l'etude, au Commissariat a l'Energie Atomique, commence a peine. Il n'y a pas tres longtemps, en effet, que nous disposons de flux relativement intenses (6.10{sup 12} neutrons thermiques par cm{sup 2}.s{sup -1} au centre de la pile de Saclay). Dans les materiaux soumis au rayonnement nous suivons l'evolution d'un certain nombre de proprietes physiques et nous etudions la retrogradation thermique, a temperature moderee, des modifications provoquees par l'irradiation. Nous nous bornerons ici a exposer nos experiences sur le graphite et le fluorure de lithium. (M.B.)
