Diffusional Properties in Technologically Advanced Intermetallics

摘要

The development of intermetallic compounds to application as structural materials inevitably requires the knowledge of relevant bulk- and grain boundary (GB) self- and solute diffusion data. During the last decade defect- and diffusion phenomena in binary nickel- and titanium aluminides have attracted much attention and self-diffusion was thoroughly investigated in numerous research papers, see e.g. overviews [1-4]. Combination of the ample experimental information and extended atomistic simulation allowed to elaborate detailed presentations on the difiusional behavior of the binary aluminides in question.
