摘要： A method and system for optimizing a simulated casting of a light weight alloy component. The simulation includes passing component design data through various computational modules relating to casting designs, process modeling and optimization, material microstructure and defects and product performance. Variations in microstructure and defects across various very small size scales are extended to increasingly larger scales to permit structural performance calculations of the cast component to take such non-uniformities into consideration. At least some of the modules employ an expert system-based approach to achieve the optimized results. The results can be compared to end user needs to determine if redesign of the part geometry or manufacturing process is needed.

摘要： Methods and technologies to maximize the aging response and the mechanical properties of aluminum alloys are provided. In one embodiment, the aging process for the slowly-quenched aluminum alloys includes, but is not limited to, at least a two-stage solution treatment and a two-stage aging hardening. In the solution treatment, the components are first heat treated at an initial solution treatment temperature and then gradually heated up to about 5° C. to about 30° C. above the initial solution treatment temperature for the material. For the aging treatment, the castings/components are first aged at a lower temperature followed by a higher temperature for the subsequent aging stages. The temperature increase during solution treatment and/or aging can be in steps, in a continuous manner, or combinations thereof. Another embodiment includes a two stage aging process in which there is a non-isothermal aging step.

摘要： A rotor for an induction motor and a method of preparing same. The method includes making a squirrel-cage rotor made up of a cage and a laminate stack by forming a mold around the stack, heating the stack and introducing a molten metal into the mold such that the molten metal substantially fills a space defined in the stack that corresponds to the cage. In one form, the space includes slots or related channels formed in the stack that upon filling with the molten metal become longitudinal bars that form electric current loops with end rings of the cage. By heating the stack and maintaining it at a temperature high enough to keep the molten metal in a substantially molten state at least long enough for it to flow through the slots of the stack, premature freezing of the molten metal is avoided. In addition, by providing low pressure to the molten metal in conjunction with the elevated temperature in the stack, flow is promoted to ensure a substantially porosity-free, fully dense squirrel-cage for the rotor.
