摘要

Al nano-particles were prepared by a dry roller vibration milling at room temperature, and the particles size milled 4 hour was the range between 50 and 80nm. The products were annealed 2 hour in the extent of 100°C–330°C. By XRD and DSC testing, we study the effect heat treatment temperature on Al particles size and microstructure. The research indicated that Al nano-particles located in metastable high energy state, because the partial mechanical energy intake the material interior in the process of vibration milling with distortion and fault. Through some heat disorder, the surface energy, strain energy and fault energy of the material can mutually conversion.In the range from 240°C to 300°C, the deposited energy was given out resulting in the material interior energy reducing.
