Novel hard metal compositions and properties. [B/sub 4/C-W-Ni-Fe; B/sub 4/C-Mo-Ni-Fe]
A new family of hard metal compositions consisting primarily of borides, borpcarbides and carbides of nickel, iron and tungsten or molybdenum is made by reaction with small quantities of boron carbide. The hardness of these compositions is in the range of the hardest conventional tungsten carbide-cobalt compositios. Denisty of this family of materials can be varied from about 8 to 17 Mg/m/sup 3/ with only slight variations in hardness. Preliminary data on hot hardness, hardness, fracture toughness, and abrasion resitance are encouraging. 9 tables.
