- Summary
- A novel hard-metal composition comprising borides and carbides of tungsten, nickel, and iron is made by reaction hot pressing mixtures of elemental tungsten, nickel, and iron powders with small quantities of boron carbide. The hardness of these compositions is in the range of the hardest conventional tungsten carbide-cobalt compositions. It was subsequently determined that molybdenum can be substituted for all the tungsten in the composition, and elemental boron can be substituted for the boron carbide with a minimum reduction in hardness. The new composition can be used in high-pressure anvils; it sustains higher pressures than commercial carbides without plastic deformation.
