High density tungsten alloy sheet |
摘要 |
A method of producing a high density tungsten alloy sheet product is disclosed which utilizes as a starting material a thin-gage sheet or foil substrate of a first alloy constituent, such as pure iron or an alloy thereof. A prescribed mixture of tungsten metal powder and a second metal alloy constitutent powder, such as nickel, is loaded on the substrate and partially consolidated in a protective atmosphere furnace to form a porous tungsten alloy skeleton which is also partially bonded to the substrate. The product is then preferably cooled in a protective atmosphere and sheared into desired lengths. The sized pieces are then further heated in a protective atmosphere at gradually increasing temperatures to a point above the melting point of the substrate, whereupon the substrate sheet or foil melts and infiltrates the porous tungsten alloy skeleton to complete the densification of the product.
