Patent ID: 10274292

Abstract:
One embodiment of the invention provides an alloy with a density greater than 10 g/cm3, the alloy comprising a single phase solution of tungsten, nickel, and iron. Also provided is a cone liner for use in shaped charges, the liner comprised of a tungsten, nickel, iron alloy having a single phase microstructure. Substantially no precipitates or second phases exist in the alloy. One embodiment of the invention further provides a method for producing a single phase alloy, the method comprising establishing a melt of iron and nickel; dissolving tungsten in the melt to form a solution; wherein the atomic percents of the nickel, tungsten and iron range from between approximately Ni-7%W-0%Fe, Ni-18%W-0%Fe, and Ni-8%W-24%Fe, wherein Ni is the remainder, maintaining the solution at a first temperature sufficient to create a homogeneous mixture; allowing the homogeneous mixture to solidify; and thermochemically treating the solidified mixture for a time to dissolve any second phases or microstructure within the mixture.
