摘要： A method of providing solution heat treatment to an aluminum alloy. A non-isothermal process is used to provide a faster heat treatment cycle time while maintaining or further improving the alloy mechanical properties after subsequent aging hardening. The process includes establishing a temperature inside a processing vessel that is greater than a soaking temperature but less than a liquidus temperature of the alloy, rapidly heating the alloy to the soaking temperature in a first heating operation, reducing the temperature inside of the processing vessel to the soaking temperature, then heating the alloy to a temperature above the soaking temperature through a gradually increasing temperature in a second heating operation. Protocols for the improved solution heat treatment may be based on one or more of computational thermodynamics, dissolution kinetics and coarsening kinetics.

摘要： A method to predict heat transfer coefficients for metal castings during quenching and/or cooling is provided. First, an initial set of HTC data are obtained from the computational fluid dynamics (CFD) simulation based on the metal casting geometry, initial metal casting temperature (distribution), quench bed/tunnel dimensions and set-up, and a given or baseline (standard) quenching condition including, but not limited to, air and/or gas flow velocity, air and/or gas flow direction relative to the work piece, air and/or gas temperature, air and/or gas humidity, etc. The initial HTC values for the entire surface of the work piece calculated from CFD can then be optimized by multiplying scale factors to minimize the error between the predicted temperature-time profiles and the experimental measurements for the given or standard/baseline quench condition. When the HTC values are optimized for a standard/baseline quench condition, a set of semi-empirical equations (or weight functions) can be used to quickly modify the standard/baseline HTC data for different quenching conditions (i.e., variations of quenching conditions from the baseline) without performing complete heat transferring and optimization calculations. A system and article of manufacture are also provided.

摘要： A ladle that can melt and freeze castable metal in a specific manner so that high quality liquid metal and metal alloys may be produced with minimum oxide and hydrogen content. Upon introduction of a quantity of molten metal into the ladle, staged heating and cooling of the molten metal promotes the liberation of previously-dissolved gases from the castable metal, resulting in significant decreases in as-cast porosity.

摘要： A plurality of conductor bars are positioned within slots of a laminated electric steel disc stack, and the ends of the conductor bars are brazed to end rings to manufacture a rotor. The method includes inserting the conductor bars into the slots of the disc stack, providing the end rings with slots for receiving the ends of the conductor bars; positioning spacers of braze material adjacent each end of each of the conductor bars to create a gap between the end rings and the steel disc stack; and applying heat to melt the braze material of the spacers whereby braze material is furnished by the spacers of braze material to braze the first and second ends of the conductor bars to the first and second end rings. Channels are provided in the face of the end rings facing the steel disc stack to drain away excess braze material.

摘要： A system includes an encoding module and a decoding module. The encoding module generates a three-dimensional (3D) model of a part, modifies the 3D model to include a 3D structure, and generates a computer-aided design (CAD) file based on the modified 3D model. The decoding module determines whether the CAD file includes the 3D structure, authorizes operation of analysis software on the CAD file when the CAD file includes the 3D structure, and prohibits operation of the analysis software when the CAD file does not include the 3D structure.
