Abstract
The structural relaxation in melt-spun Co80-xCrxB20 (x=20, 25 or 30) a morphous alloys was investigated by measuring the residual electrical resistance (liquid-N-2 temperature). The reversibility, the specific l ogarithmic kinetics and the cross-over effect were confirmed for the c hemical short-range ordering (CSRO) process Co50Cr30B20 alloy. Isother mal measurements were performed mainly for this alloy, and the results were interpreted by the activation energy spectrum model. Spectra of activation energy showing three peaks were obtained by numerical calcu lations based on Lagrange multipliers.
