VEGARD LAW APLICABILITY IN CRYSTAL PARAMETER
DETERMINATION FOR MECHANICALLY ALLOYED
POWDERS
The performed investigations prove that applying the Vegard Law for
Cr-Fe binary alloys result values of crystal parameter in good concordance with
experimental results. This makes Vegard Law a useful theoretical tool for
estimation of crystal properties of further alloys. The viability of this law could
not be proved for ternary systems. We mention that Al and Co were introduced
as ternary component after 16 hours of previous milling of Fe-Cr powder
composition. The adding of ternary element such Al or Co at the beginning of
milling experiment is an open path for further investigation of the applicability of
Vegard Law to the ternary systems.
