摘要：

The recrystallization behavior of cold-rolled Al-(0.04-6.0)%Ni alloys was studied using mechanical spectroscopy, microstructural studies, and hardness measurements. Temperature dependencies of internal friction at heating demonstrate a 'pseudo' peak related to recrystallization start temperature. An increase of Al3Ni particles fraction from 0.1 to 7-10 % decreases recrystallization start temperature from 297 to 210 degrees C and provides significant grain refinement due to particle-stimulated nucleation mechanism. The hardness and microstructure evolutions during heating exhibit a strong correlation with temperature and time dependent internal friction behavior. The Avrami model was applied to compare the recovery and recrystallization behavior of the studied alloys.
