Ordering phenomena in alloys: Access to kinetic parameters and atom-jump processes

Ordering phenomena have a broad range of cross-cutting implications in allo ys; aside from information on the establishment of order (short- and long-r ange order), information can be gained on the atom-jump processes involved as well as on the defect parameters that control ordering kinetics. Residua l resistometry is an excellent tool with adequate ultrahigh accuracy for st udying fine variations of order far below the order-disorder transition tem perature or the subtle variations of short-range order corresponding to tin y changes off he atom distribution in concentrated solid solutions outside any long-range order phase. Residual resistometry measurements are also wel l suited for obtaining information on how to heat-treat a material to achie ve stable states before applying any other time-consuming method.
