International Classification:

B29C 43/02
B28B 3/00

US Classification:

425 77, 4254052

Abstract:

An improved method and container for forming billets using hot isostatic pressing is provided. The improved method and container have features that control the deformations of the container during the high temperatures and pressures experienced in such processing so as to provide a billet having a predetermined shape such as, for example, substantially parallel, convex, and/or concave sides. Conservations of the powder used for the billet and more efficient use of the container upon the resulting billet can be achieved.

US Classification:

164133, 164135, 164335, 1641552

Abstract:

A mold system and method for producing a casting. The mold system utilizes multiple channels, each channel comprising a sprue and gating system, to feed the mold cavity at different heights. When a lower portion of the mold is filled, a controller is signaled to initiate filling of the mold through a second channel positioned above the lower portion. This mold system desirably provides the hottest molten metal to the last portion of the casting to freeze with or without the use of risers, eliminating casting defects. The system also enables the controlled pouring of dissimilar metal castings.

International Classification:

C21D 6/00

US Classification:

266258, 148640

Abstract:

A system for heat treating an alloy steel component includes a first enclosure and a second enclosure opposed to the first enclosure. The first and second enclosures define a chamber around only a portion of the alloy steel component. The system further includes a heating element in the chamber to heat the portion of the alloy steel component. A method for heat treating an alloy steel component includes placing a first enclosure against a first side of the alloy steel component and placing a second enclosure against a second side of the alloy steel component. The method further includes creating a substantially airtight chamber around only a portion of the alloy steel component between the first and second enclosures and heating the portion of the alloy steel component inside the substantially airtight chamber.

Abstract:

A method of making an austempered ductile iron article is disclosed. The method includes providing a melt of a ductile iron alloy composition. The method also includes casting the melt into a mold to form a casting. The method further includes cooling the casting to an austempering temperature by circulating a coolant through the mold; wherein cooling comprises solidifying the melt and forming a ductile iron article. Still further, the method includes heating the casting to maintain the austempering temperature for an interval sufficient to form an austempered ductile iron article that comprises a microstructure comprising ausferrite.
