A system and method for friction stir processing of a hand-held cutting edge, wherein friction stir processing techniques are used to modify the properties of the hand-held cutting edge to obtain superior edge retention and superior resistance to chipping of the hand-held cutting edge.

Solid state processing of hand-held knife blades to improve blade performance

A system and method for using friction stir welding, friction stir processing, and friction stir mixing to create pressure vessels, pipes or other containers comprised of a single material or multiple layers of different materials, and having superior strength and endurance characteristics.

Method for construction of pressure vessels with a liner using friction stirring processes

The present invention relates to a method of joining segments of high melting temperature materials, that includes frictionally heating a first high melting temperature material and a second high melting temperature material wherein the first high melting temperature material and second high melting temperature material are welded together, without substantially changing the macrostructure and/or the microstructure of the first high melting temperature material and the second high melting temperature material, after application of a frictional force.

Applications of friction stir welding using a superabrasive tool

A method for manufacturing a PCD bit by isostatically or mechanically press forming a green on a metallic blank. A metallic blank is vertically suspended into a flexible vessel. Powder metal is mixed with a binder and introduced into the flexible vessel surrounding the lower end of the suspended metallic blank. The vessel is then isostatically or mechanically pressed causing the powder mixture to stick together and to the blank, forming a green on the blank. The blank and green are removed from the vessel and the exposed end of the metallic blank is chucked onto a milling machine and turned for milling the green into the shape of a PCD bit head. After the milling is completed, the green and blank are sintered, hardening the bit head shaped green and strongly bonding it to the metallic blank, forming a PCD bit wherein the hardened green is the bit head while the metallic blank is the bit pin.
