A researcher who, with <Motomasa Fuse>, studied how microstructure affects irradiation growth in zirconium alloys. Their model linked atomic-scale <point defects> to macroscopic deformation and compared predictions with experiments. It predicted less growth for larger grains, reduced grain aspect ratio or lower <dislocation> density, showing why a material's processing history can matter alongside its chemical composition.<Effects of Microstructural Factors on Irradiation Growth in Zirconium-Base Alloys by Noriyuki Sadaoka and Motomasa Fuse>[Abstract: microstructural changes predicted to reduce irradiation growth]{ref}
