In this work the effect of TiN particle size on its sintering and properties using
nanodispersed (average particle size 40 nm) and micrometric dispersion TiN powders is
studied. Sintering was carried out on a SPS machine (Sumitomo) at 1600 ºC with a
temperature rise rate of 100 ºC/min. Sintering studies have shown that the density of the
sample obtained using mixtures of both powders is higher than in the case of pure raw
materials. In addition, samples with 30% by weight of nanopowder have the highest density. In
contrast, the hardness of the samples reaches the highest values at 50-80% by weight of the
nanopowder. The grain size is also the smallest for samples containing 30-70% by weight of
nanopowder.
