Abstract

The powder of supersaturated solid solution of Al-7.8at%Ti-0.3at%Fe with a nanocrystalline, prepared by MA,was compacted to columnar shape material at low temperature by application of high pressure of 3GPa. Diffusion of copper was studied in this compacted nanocrystalline material using and ion mass microanalyzer. The interfacial diffusion coefficient of copper in the nanocrystalline materials is fairly higher than the volume diffusion coefficient of copper in aluminum, and the activation energy of the interfacial dirrusion is quite small when compared with that of volume diffusion of copper in aluminum.
