Effect of Ultrasonic/Electromagnetic Energy-Field on Structure Andproperties of Cast-Rolled 3003 Aluminum Alloy Strips

Abstract:

The plates under the compound energy field and the general ones were prepared by introducing ultrasonic and electromagnetic field at the key part of the cast-rolling area, and then the final aluminum strips with thickness of 0.27 mm were prepared through cold rolling and annealing. The microstructures and properties were investigated by optical microscope (OM), static/dynamic universal testing machine and scanning electron microscope (SEM). The results show that by applying compound energy-field, grains are significantly refined and the mechanical properties are improved. Compared to the general cast-rolling strips, the ultimate tensile strength, yield strength and elongation of compound energy-field aluminum strips are improved by 32.93%, 38.91% and 6.25%, respectively.
