In this work, experimental evidence is presented that demonstrates the significant effect of such interactions upon (1) the specific properties desired of special grain boundaries (e.g. resistance to corrosion) and (2) the resultant grain boundary character distribution following materials processing. Regarding the latter, it is shown how solute-grain boundary interactions impact significantly on the delicate balance of geometric (crystallographic), energetic, and kinetic influences, which ultimately dictates the grain boundary character distribution of engineered materials. 关键词: NHS NANOGOLD; PEPTIDE RECEPTORS; NEUROPEPTIDES; GOLD LABELING; NONRADIOACTIVE METHOD; RAT NONRADIOACTIVE METHOD; RAT; HIGH-PURITY NICKEL; NANOCRYSTALLINE NICKEL; CORROSION; DISCLINATIONS; STABILITY; ALUMINUM; BEHAVIOR; DESIGN; NI STABILITY; ALUMINUM; BEHAVIOR; DESIGN; NI
