Řešitel: RNDr. Jiří Čermák, DSc.
Číslo projektu: 106/01/0384
Agentura: Grantová agentura České republiky
Doba řešení: 01. 01. 2001 - 31. 12. 2003
Sloučenina Ni3Ga je zvolena jako vhodný systém modelující vztah mezi vlastnostmi bodových poruch a difuzivitou složek v intermetalikách se strukturou L12. Z čistých složek bude připravena řada slitin v koncentrační oblasti existence sloučeniny Ni3Ga.
