Cooperative Radiation Effects Simulation Program.
Abstract
The goal of the research is to provide the theoretical and experimental bases for understanding the mechanisms of void nucleation and growth and the influence of helium on both mechanical properties and void nucleation, as well as a theoretical insight into energy deposition processes. This report includes (1) an investigation of temperature-dependent effects in nickel-ion bombarded nickel, (2) comparisons of nickel-ion damage in nickel produced by a scanned-beam with that produced by a steady defocused beam, (3) the use of Jacobi polynomials to obtain a new approximation technique for transport equations, (4) investigation of the effects of cyclotron-injected helium on the fatigue properties of a TZM alloy, (5) improved facility for ion-beam irradiations, (6) a theory of the influence of minor alloy additions on void formation, (7) extension of the alpha-alpha elastic scattering technique for measuring helium concentration profiles to the study of thermal diffusion of helium, and (8) an improvement in the NRL energy deposition code E-DEP-1 and progress on a transport theory for energy deposition.
