Investigator: RNDr. Jiří Čermák, CSc., DSc.
Number of Project: OC P3.110
Agency: Ministry of Education, Youth and Sports
Duration: 01. 01. 1999 - 31. 12. 2001

The aim of the project is to contribute to better understanding of grain boundary diffusion mechanisms. The main attention will be paid to atomic movement along grain boundaries in modified Ni - Al intermetallics. An influence of segregated atoms upon the energetics of grain boundary diffusion will be taken into consideration.
