| 20110289997 | METHOD AND APPARATUS FOR FABRICATING ARTICLES FROM METALS HAVING A HEXAGONAL CLOSE PACKED CRYSTAL STRUCTURE - A method and apparatus for fabricating articles from metals having a hexagonal close packed (HCP) crystal structure is described. The method comprises a two-stage process: specialized hot deep drawing and pneumatic coining within a single press cycle. The apparatus includes a drawing chamber in which the environmental temperature is sufficient to impart enough ductility to the metal or alloy blank to allow it to be drawn about a plug into an outline shape of the finished part. More detailed features are then added by increasing the gas pressure inside the chamber, thereby forcing the drawn blank more closely against the contours of the plug. Use of pneumatic pressure avoids the use of matched dies, which are prohibitively complex and expensive to use to shape parts from such HCP metals. | 12-01-2011 |
| 20120067101 | FORGING TOOL - A forging tool for precision forging of components of intermetallic or high-temperature stable phases with high yield stresses and shapeable at temperatures up to 1400° C. is made of graphite with a low-melting metal or a low-melting metal alloy infiltrated into its open-pored cavities, where metal carbides are created by heat treatment and form with the graphite a two-phase material hardened by subsequent quenching. The tool features high strength thanks to the yield stress increasing as the temperature increases at forging temperatures up to 1400° C., and is oxidation-resistant. It is electrically conductive, and has a low heat capacity, so that rapid inductive heating of the tool involving only low energy expenditure, short forging cycles and an inexpensive isothermic shaping process are possible. It has good lubrication properties, low wear and low manufacturing costs. | 03-22-2012 |
