Spark plasma sintering of TixTa1-xC0.5N0.5-based cermets: Effects of processing conditions on chemistry, microstructure and mechanical properties

Nanometric powdered TixTa1-xC0.5N0.5-based cermets were fabricated using a mechanically induced self-sustaining reaction and consolidated by spark plasma sintering. Highly dense cermets were obtained, and their chemistry, microstructure and mechanical properties were characterised by X-ray diffracti...
