  • Resistance heated stir welding
    Patent number: 5829664
    Abstract: A method for welding together two workpieces includes the steps of abutting workpieces together along respective edges of each of the workpieces, and locating one end of a rotatable tool astride the edges and against the workpieces. The tool is provided with a relatively narrow pin extending from the working end of the tool to engage the workpiece edges. The tool and pin are rotated to heat the workpiece edges, and the tool and workpieces are relatively moved. Electric current is supplied between the workpiece edges and the pin, with electrical resistance occurring between the workpiece edges and pin to provide heat in addition to the heat generated by friction occurring between the pin and workpieces to weld the workpieces together.

  • Monolithic metal matrix composite
    Patent number: 5746267
    Abstract: Metal matrix composites are manufactured in a vacuum die casting machine. Solid aggregate material is placed in a die, the die is evacuated, and molten metal is driven by a piston to infiltrate the solid aggregate material where it subsequently solidifies to form a metal matrix composite.

  • Fabrication of metal matrix composites by vacuum die casting
    Patent number: 5259436
    Abstract: Metal matrix composites are manufactured in a vacuum die casting machine. Solid aggregate material, at least 65 volume percent, is placed in a die, the die is evacuated and heated, and molten metal is driven by a piston to infiltrate the solid aggregate material where it subsequently solidifies to form a metal matrix composite.
