Variation of the size and shape of the carbide grains of a chromium carbide-nickel hard metal during sintering

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

The sintering of a Cr3C2-15% Ni hard metal is accompanied by increases in the area, perimeter, and diameter of sections of its carbide grains; the mean value of dimensionless form factor of the grains remains unchanged during the process. At the same time sintering intensifies the size and shape heterogeneity of the carbide grains: It increases the amount of both large carbide grains and grains of elongated shape with small value of form factor, which are characterized by low strength.
