Abstract: A powdered magnesium composition is mixed with lithium dispersed in an inert, non-water absorbent, liquid medium to produce a substantially homogenous admixture that is heated to melt the lithium and vaporize the liquid medium to thereby obtain a decovered powdered alloy comprising aluminum and lithium. The liquid medium has first and second liquid constituents, wherein the first liquid constituent has a boiling point below the melting point of lithium and the second liquid constituent has a boiling point above the melting point of lithium but below the melting point of the alloy being produced.

Abstract: A powdered aluminum composition is mixed with lithium dispersed in an inert, non-water absorbent, liquid medium to produce a substantially homogenous admixture that is heated to melt the lithium and vaporize the liquid medium to thereby obtain a decovered powdered alloy comprising aluminum and lithium. The liquid medium has major and minor liquid constituents, wherein the major liquid constituent has a boiling point below the melting point of lithium and the minor liquid constituent has a boiling point above the melting point of lithium but below the melting point of the alloy being produced.

Abstract: A method is provided for preparing computer disk substrates having low surface amplitude which comprises: (a) forming a liquid suspension containing aluminum powder, an aluminum alloying element and a borate composition by initially admixing the borate composition with a volatile liquid medium to obtain a borate solution and thereafter admixing the aluminum powder and aluminum alloying element with the borate solution to produce the liquid suspension; (b) heating the liquid suspension to remove the liquid medium and to obtain a dry aluminum powder composition; (c) isostatically pressurizing the dry aluminum powder composition and roller compacting the same into sheet form; (d) heating and sintering the sheet form in a non-oxidizing atmosphere; and (e) cutting and compressing the sintered sheet into computer disk substrate configuration.

Abstract: Hollow magnetic pipe having a magnetic field extending across the hollow of the pipe is prepared by a multistep process which includes (a) forming first and second pipe halves from ductile and magnetizable sheet metal, (b) placing the pipe halves in pipelike alignment and joining each pair of adjacently disposed, opened edges thereof with a nonmagnetic seam to form a hollow pipe, (c) conditioning the hollow pipe to receive and maintain a permanent magnetic state, and (d) subjecting the conditioned hollow pipe to a magnetic field whereby the side walls abutting one nonmagnetic seam acquire a permanent north magnetic pole configuration and the side walls abutting the other nonmagnetic seam acquire a permanent south magnetic pole configuration. The hollow magnetic pipe is adapted for use as a conduit for conveying conductive fluid in magnetohydrodynamic energy amplification systems.
