摘要: A method of making a large Mo billet or bar for a sputtering target wherein two or more bodies comprising Mo are placed adjacent one another (e.g. stacked one on the other) with Mo powder metal present at gaps or joints between the adjacent bodies. The adjacent bodies are hot isostatically pressed to form a diffusion bond at each of the metal-to-Mo powder layer-to-metal joint between adjacent bodies to form a billet or bar that can be machined or otherwise formed to provide a large sputtering target. The number and dimensions of the Mo bodies placed adjacent one another are selected to yield a desired large size the billet or bar suitable for the sputtering target. The billet or bar for the sputtering target exhibits a microstructure comprising equiaxed grains of less than 30 microns grain size and exhibits a low oxygen content of less than about 100 ppm by weight.

摘要: Composite mold for use in casting a metal or alloy includes an inner mold region that includes a mold cavity and a fugitive metallic outer backup mold region residing on the inner mold region, wherein the metallic material of the backup mold region has such a melting temperature that the backup mold region melts from the inner mold region after the molten metal or alloy is cast and at least partially solidified in the mold. The inner mold region can comprise a non-metallic refractory or ceramic shell mold, while the backup mold region can comprise tin or other relatively low melting point metal or alloy.

摘要: The oxidation resistance of a superalloy casting such as an equiaxed, directionally solidified, or single crystal casting, is improved by melting, pouring, or casting the alloy so as to react with a magnesium or calcium-bearing ceramic material. Magnesium or calcium is introduced into the alloy through a controlled reaction between the alloy and the magnesium or calcium-bearing ceramic material.

摘要: A method of making a composite casting wherein a casting mold is provided having a melt-receiving mold cavity and a preformed metallic or intermetallic insert located in a predetermined position in the mold cavity. A melt is introduced into the mold cavity about the insert and is solidified to provide a composite casting having one or more interfaces between the insert, or an insert positioning member, and cast/solidified metal about the insert. The interface is exposed on or communicates with an exterior surface of the composite casting. After separation from the mold, the composite casting is subjected to a sealing operation to gas-tight seal the interface(s) at the exterior casting surface. For example, the interface can be sealed by providing fused material at the interface. After the interface(s) is (are) sealed, the composite casting is subjected to elevated temperature and isostatic gas pressure conditions effective to produce a sound, void-free, contamination-free metallurgical bond between the insert and the cast melt thereabout. The previously sealed interface(s) prevent the pressurizing gas from entering and migrating between the insert and the cast melt so as to enable formation of the sound, void-free, contamination-free bond.
摘要翻译: 一种制备复合铸造的方法,其中提供具有熔体接收模具腔的铸模和位于模腔中的预定位置的预成型金属或金属间插入件。 将熔体引入到模具腔内,并且固化,以提供在插入件或插入件定位构件之间具有一个或多个界面的复合铸件和围绕插入件的铸造/固化金属。 该界面暴露在复合铸件的外表面上或与复合铸件的外表面连通。 在与模具分离之后,对复合铸件进行密封操作,以在外部铸造表面上气密地密封界面。 例如,可以通过在界面处提供熔融材料来密封界面。 在密封界面之后,复合铸件经受高温和等静压气体压力条件,有效地在插入件和铸造熔体之间产生声音,无空隙,无污染的冶金结合。 先前密封的界面防止加压气体进入和移动插入件和铸造熔体之间,以便形成声音,无空隙的无污染的粘合。

摘要: Titanium based and nickel based castings are made by casting a suitable melt having a relatively low melt superheat into a mold cavity defined by one or more low carbon steel or titanium mold members where the melt solidifies to form the desired casting. The melt super-heat is limited so as not to exceed about 150.degree. F. above the liquidus temperature of the particular melt being cast. For a steel mold, one or more titanium melt inlet-forming members are provided for cooperating with the steel mold members to form an melt ingate that communicates to the mold cavity for supplying the melt thereto in a manner to avoid harmful iron contamination of the melt during casting. The mold body-to-mold cavity volume ratio is controlled between 10:1 to 0.5:1 to minimize casting surface defects and mold wear/damage.

摘要: A method of joining metal materials by spraying molten metal into a cavity between the articles to be joined. Prior to deposition of the metal, the surface of the cavity is cleaned and the articles to be joined are preheated. Subsequent to deposition of the metal within the cavity, the joined articles are cooled at a rate that precludes damage due to thermal effects and the deposited metal is consolidated in the cavity by hot pressing.
