摘要： An alloy includes aluminum, a rare earth element, and an alloying element selected from the following: Si, Cu, Mg, Fe, Ti, Zn, Zr, Mn, Ni, Sr, B, Ca, and a combination thereof. The aluminum (Al), the rare earth element (RE), and the alloying element are characterized by forming at least one form of an intermetallic compound. An amount of the rare earth element in the alloy is in a range of about 1 wt. % to about 12 wt. %, and an amount of the alloying element in the alloy is greater than an amount of the alloying element present in the intermetallic compound.

摘要： A product includes an aluminum alloy having an anodized layer. The alloy has a bulk composition including at least 1 wt. % of one or more rare earth elements (REEs). A product includes microstructures extending across a boundary defined between an anodized layer and an unoxidized alloy. Each microstructure includes an intermetallic phase transitioning to an oxidized intermetallic phase across the boundary. A product includes an anodized layer where up to 90% of a thickness of the layer includes voids resulting at least in part from dissolution of a rare earth element oxidized intermetallic phase. The voids are in a morphology of the dissolved oxidized intermetallic phase.

摘要： A product includes a material having aluminum and at least one rare earth element (REE). The material includes the following microstructure features: at least 1 volume % particles of a phase of an aluminum-rare earth element alloy, the particles comprise at least 5 weight % of the at least one rare earth element, the particles have an average aspect ratio less than or equal to 5, and an average interparticle spacing between the particles is less than or equal to 1 μm. A method includes forming a base material, the base material having aluminum and at least one rare earth element (REE), and working the base material to form a product.
