Diffusion properties of intermetallics with L1₂ structure: Ni₃Ga as a model system

Investigator: RNDr. Jiří Čermák, DSc.
Number of Project: 106/01/0384
Agency: Czech Science Foundation
Duration: 01. 01. 2001 - 31. 12. 2003

Ni₃Ga is used as a model compound for intermetallics with L1₂-structure to study the interrelationship between point defects and diffusion properties. Therefore a series of samples with different composition within the homogeneity range of Ni₃Ga will be prepared.
