Effect of Lanthanum on Secondary Phase Modification and the Mechanical Properties of 6082 Aluminum Alloy
Source abstract
Abstract
The effect of the rare earth element La on α-Al grain refinement, secondary phase modification, and the mechanical properties of 6082 aluminum alloy have been investigated. The results showed that addition of La can both refine the α-Al grains and modify the secondary phase morphology. The size of the dendritic grains was significantly refined compared with that of the La-free alloy. When the La content was 0.2 wt.%, the α-Al grains showed the best refinement effect, and the volume fraction of the long-strip β-AlFeSi phase was significantly lower because the β-AlFeSi phase was efficiently modified to the α-AlFeSi phase. Excellent comprehensive mechanical properties were obtained at a La content of 0.2 wt.%. Addition of 0.2 wt.% La to 6082 aluminum alloy can simultaneously achieve α-Al grain refinement and secondary phase modification, which improves the mechanical properties.
