摘要： Embodiments of surface-hardened aluminum-rare earth alloys and methods of making the alloys are disclosed. In some embodiments, the alloy comprises aluminum and 4 wt % to 60 wt % of a rare earth component X having a maximum solid solubility of ≦0.5 wt % in aluminum. The surface-hardened alloy component has an alloy bulk portion and a hardened alloy surface portion. At least a portion of the hardened alloy surface portion has a Vickers hardness that is at least 30% greater than a Vickers hardness of the alloy bulk portion.

摘要： Described herein are additive manufacturing methods and products made using such methods. The alloy compositions described herein are specifically selected for the additive manufacturing methods and provide products that exhibit superior mechanical properties as compared to their cast counterparts. Using the compositions and methods described herein, products that do not exhibit substantial coarsening, such as at elevated temperatures, can be obtained. The products further exhibit uniform microstructures along the print axis, thus contributing to improved strength and performance. Additives also can be used in the alloys described herein.

摘要： Aluminum-copper-manganese-zirconium alloys for metal additive manufacturing include 5 wt % to 35 wt % copper, 0.05 wt % to 3 wt % manganese, 0.5 wt % to 5 wt % zirconium, 0 wt % to 3 wt % iron, and 0 wt % to less than 1 wt % silicon, with the balance being aluminum. The as-printed alloys may have a microstructure comprising θ′ intermetallic precipitates having an average diameter of 0.1 μm to 0.3 μm, a microstructure comprising θ intermetallic particles having particle spacing of 50-500 nm with a volume fraction of 0-50%; a microstructure comprising a bimodal distribution of equiaxed grains and columnar grains, or any combination thereof. The as-printed alloys may exhibit superior mechanical properties compared to cast alloys with a similar composition.
