Abstract
In this work high purity and nanometer character titanium carbonitride TiCxN1-x powders were obtained by mechanically induced self sustaining reaction (MSR) in a high-energy planetary ball mill, from a mixture of titanium with graphite or carbon nanofiber (CNFs) in a nitrogen atmosphere. A promising method for developing these materials is the coupling of the MSR with SPS sintering technique. The product is sintered at 1400 ºC and 1700 ºC, obtaining a completely dense monolithic ceramic ( > 99% t.d). In this work, the influence of SPS treatment and carbon precursor on material microstructures was studied and the main mechanical properties of the end material were evaluated.

En el presente trabajo se han obtenido carbonitruros de titanio TiCxN1-x de alta pureza y con carácter nanométrico, por molienda reactiva (MSR) de alta energía en un molino planetario, a partir de la mezcla de titanio con grafito o nanofibras de carbono (CNFs) en una atmósfera de nitrógeno. Una metodología prometedora para el desarrollo de estos materiales consiste en el acoplamiento de la técnica MSR con el sinterizado por SPS. El producto obtenido se ha sinterizado a 1400 ºC y 1700 ºC, obteniéndose una cerámica monolítica totalmente densa ( > 99% d.t). En este trabajo se analizan las distintas microestructuras obtenidas en función del precursor de carbono y el tratamiento de SPS, evaluando las principales propiedades mecánicas de los materiales resultantes.
