| Number | Title | Issue Date |
| 7322223 | Creep forming a metallic component A method of creep forming a metallic component is provided. The method includes the steps of applying static loading and cyclic loading and/or vibration to the component during the creep forming thereof to act as a source of additional energy. ... | 01/29/2008 |
| 6410154 | Tial-based alloys with excellent oxidation resistance, and method for producing the same The invention relates to TiAl-base alloys with excellent oxidation resistance, and a method for producing the same. The TiAl-base alloy of the invention comprises a substrate and a surface part formed on the substrate, the surface part comprising at least... | 06/25/2002 |
| 6264771 | Process for forming a plate-like component This invention provides a method of forming a component made of an artificially and plastically formable material which can be hardened by artificial aging. The component is first shot-peen-formed in the unhardened condition and is subsequently, artificia... | 07/24/2001 |
| 5733392 | Method of surface treating metal parts An apparatus is disclosed for carrying out a method whereby parts are treated in a fluidized bed created within an enclosure that provides for movement of air generally upwardly through the enclosure, and where the parts are passed through the fluidized b... | 03/31/1998 |
| 5405428 | Decontamination and/or surface treatment of metals The invention relates to a process of decontaminating metal (especially aluminum or aluminum alloy) scrap contaminated with organic material. The problem with such methods is that undue oxidation of the metal may take place as the decontamination proceeds... | 04/11/1995 |
| 5346563 | Method for removing sulfur from superalloy articles to improve their oxidation resistance Superalloy articles are made more oxidation resistant by a process which includes heat treating the article in the presence of foreign chemical species, at a temperature at which the foreign chemical species reacts with and modifies any oxide film present... | 09/13/1994 |
| 4717433 | Method of cooling a heated workpiece utilizing a fluidized bed A fluidized bed of solid particulate material cools a heated workpiece through a temperature range critical to strength property determination. Upon immersion into the fluidized bed container the bed is allowed to collapse around the workpiece forming a u... | 01/05/1988 |
| 4620883 | Fluidized-bed heat-treatment method for metallic workpieces A metallic object is heat treated by suspending it in a fluidizable bed through which a gas can be passed at a volume/time rate to fluidize it. The temperature of the bed is varied in accordance with a temperature curve having regions of considerable slop... | 11/04/1986 |
| 4612065 | Method for the heat treatment of workpieces A method is described for the heat treatment, preferably for the intermediate heat treatment, of workpieces, in which the workpieces coming from a heating apparatus are quenched in a fluidized bed under precise temperature and movement control, and then, ... | 09/16/1986 |
| 4379725 | Process for hot isostatic pressing of a metal workpiece A process for hot isostatic pressing of a metal workpiece, such as a ferrous casting. The workpiece is heated in a fluidized particulate bed (sand) to a temperature above the plastic range of the metal (e.g. 2000° F.). Then, the workpiece in the unfluidi... | 04/12/1983 |
| 4340433 | Method of heat treating articles This invention relates to a method of heat treating articles which utilizes a fluidized bed comprising a container containing a mass of refractory particles and having a porous base, a layer of such particles adjacent to the porous base being formed of he... | 07/20/1982 |
| 4029524 | Heat treating process for a rod within a fluidized bed A heat treating process for a rod by the use of a fluidized bed consisting of alumina, silicon sand, zircon sand, and the like, is disclosed for adjusting the strength of the rod due to its cooling within the fluidized bed. While prior art heat treatment ... | 06/14/1977 |
