The Annealing Behavior of cryoECAP Processed Pure Aluminum under High Magnetic Field

摘要

The property and microstructure of pure Al prepared by the cryogenic ECAP after annealing at different temperatures and times with and without the application of 12T high magnetic field were investigated by hardness test and optical microscopy observation. The results show that with the application of high magnetic field, the hardness of cryo-ECAPed pure Al is lower than that of material annealing without high magnetic field. The high magnetic field accelerates crystallization of cryo-ECAPed pure Al during annealing.
