By using differential scanning calorimetry (DSC), energetic and kinetic measurements associated with the different peaks displayed during linear heating of Cu-4 at.% Ti were made, employing quenched and cold-work material at different percentages of cold rolling. Unlike to the situation observed in the quenched alloy in which precipitation is developed, in the deformed alloy Such process is inhibited by the segregation of the solute atoms to partial dislocations. For calculating the dislocation density an expression governing the energy release accompanying recrystallization was applied, in order to determine, by appropriate models, the energy evolved during the pinning process. |
