Definitions

  • the present invention relates to a method for reducing the dispersion of the values of the mechanical characteristics of tungsten-nickel-iron alloys.
  • This process is characterized in that cobalt and manganese powders are added together to the initial powder.
  • the elastic limit Rp, the tensile strength Rm and the elongation A% were measured on the products after each of the following steps: sintering - degassing - wrought - tempering, identified in Figures 2 and 3 respectively by means of the letters A , B, C, D.
  • the breaking strength Rm was measured in MPa, the elastic limit Rp 0.2 in MPa, the Vickers hardness in HV30, the elongation in%.
