Abstract

The pseudoternary system “HfO”−HfN−HfC and the corresponding pseudobinary systems “HfO”−HfN, “HfO”−HfC and HfC−HfN have been examined by metallographic and X-ray methods within the temperature range of 1600 to 2000°C.

The field of homogeneity for the hafniumoxicarbonitrides is not extended. The oxygen content of the solid solutions decreases from hafniumoxicarbides to hafniumoxinitrides. The miscibility ends at 1600°C for HfC0.75O0.25 and HfN0,80O0.20 and at 2000°C for HfC0.70O0.30 and HfN0.75O0.25 resp.
