Paper Title:
Microstructural Analysis of Hardmetal Using WC Nanometric Powders
  Abstract

Nanometric powders of WC with 10 weight% Co were mixed in high-energy mill. Compaction was performed at 200MPa and processed by the technique of high pressure and high temperature (HPHT). Sintering conditions were P = 5GPa, T = 1300-1400-1500° C, t = 2-4 min. For comparative purposes, samples were conventionally sintered at T = 1400° C, t = 45 min, vacuum of 10-2 mbar.
