  • Process for purifying metal compositions
    Patent number: 4572818
    Abstract: Purified metal compositions and metal compositions free of secondary phase material are produced by heating a metal alloy from the nonequilibrium solidus temperature while subjecting the liquid-solid mixture to high pressure and forcing the liquid through a filter. Compositions obtained by the process of this invention have a nondendritic structure which can be substantially free of secondary phase material.

  • X-ray tube target
    Patent number: H547
    Abstract: A composite target for an X-ray tube has a graphite substrate portion and a metal portion, the two portions being bonded together by successive interspersed layers of platinum and tantalum. The platinum layer is disposed between the graphite substrate portion and the tantalum layer. The tantalum layer acts to bond the metal portion to the platinum layer and also acts as an isolator to prevent the formation of carbides by migration through the bonding layers.
