Effect of Efficient Purification on Mechanical Properties of 3003 Aluminum Alloy

Abstract:

3003 aluminum melt was treated with efficient purification, and it was deformed by isothermal compression in the range of deformation temperature 300-500 °C at strain rate 0.0l-10.0 s^-1 with Gleeble-1500 thermal simulator. The results show that efficient purification treatment can significantly reduce the impurities, and make inclusion size smaller, uniform distribution. Room temperature mechanical properties were significantly improved. At the same strain rate, the flow stress of 3003 aluminum alloy decreases with the increase of deformation temperature. The flow stress increases with the increase of strain rate under the same deformation temperature. Two kinds of 3003 aluminum alloys with different purification treatments both have dynamic recrystallization characteristics. Especially when the strain rate reaches 10.0 s^-1, the rheological curve appears sawtooth fluctuation and the alloy may have discontinuous dynamic recrystallization.
