Investigator: RNDr. Jiří Čermák, DSc.
Number of Project: 106/03/1355
Agency: Czech Science Foundation
Duration: 01. 01. 2003 - 31. 12. 2005

The aim of the project is to study diffusion processes in Mg-Al-X alloys. Measurements are caried out both with model and commercial alloys. Coefficients of volume diffusion and diffusivities along short-circuit paths are measured by residual activity method, interdiffusion coefficients by diffusion couple technique.
