摘要：
The spinodal decomposition processes in the rapidly solidified CU-10at%Co alloy aged at several temperatures have been investigated using an in-situ electrical resistance measurement method combining a slowly scanning x-ray diffraction technique. Based on the Calin-Hilliard theory, the time-dependences of amplification factor of the concentration modulation R(beta) at different aging temperatures were calculated, and the Co atomic concentration of Co-rich region and Co-depleted region in the aged alloy were also deduced. The results showed that the evolution of composition modulation in microstructure m Cu-10at%Co alloy can be monitored and characterized by an in-situ electrical resistance measurement method if only the degree of phase decomposition at some aging temperature and aging time had been previously detected.
