Abstract
Structure formation during the sintering of ZrN-Cr and HfN-Cr composites in argon was studied Due to insufficient wetting of the the solid nitride fra meworks by the liquid phase, and the evolution of nitrogen from ZrN and HfN , the composites retained high porosity (more than 15%). Sintering was acco mpanied by a rapid reaction of chromium with evolved nitrogen, and also wit h Zr and Hf to form the intermetallics ZrCr2 and HfCr2.
