Also, the microstructure was characterized by transmission electron microscopy (TEM). Effect of Al2O3 reinforcement on the aging kinetics was also evaluated. It was found that Cu\u20133wt.%Cr and Cu\u20135wt.%Cr solid solutions undergo spinodal decomposition at initial stages of ageing. However, decomposition mechanism was changed to nucleation and growth by the aging progress. The aging kinetics for the Cu\u2013Cr\/Al2O3 composition appeared to be slightly faster than that for Cu\u2013Cr, since the ageing activation energy is decreased in presence of Al2O3 nano-particles. This behavior is probably due to the higher dislocation density and other structural defects previously produced during ball milling. A detailed comparison of the DSC results with those obtained by TEM, showing good consistency, has been presented. The average size of Cr-rich precipitates was about 10 nm in the copper matrix.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this study, spinodal decomposition and precipitation mechanism of mechanically alloyed supersaturated Cu\u20133wt.%Cr and Cu\u20135wt.%Cr solid solutions was investigated under nonisothermal aging.
