Influence of a weak pulsed magnetic field on the recovery and recrystallization in aluminum

Pulsed Magnetic Field (PMF) is an easy and effective method for changing the properties of various materials. In this work we present the influence of a weak pulsed magnetic field (WPMF) on the recovery and recrystallization processes in 99.99% aluminum. The state of the material before and after processing was determined by the method of Internal Friction (IF). It was found that if WPMF is carried out simultaneously with heating and annealing of deformed aluminum, then the recrystallization process is observed at lower temperatures. Pre-treatment with WPMF for 72 hours before annealing reduces the height of the IF peak and causes a more intense decrease in the level of IF at temperatures of 350°-400°C. Thus, the aftereffect of the WPMF during the recrystallization of deformed aluminum can be monitored.
