Preface

From the two last decades, elaboration techniques based on the use of high current intensities, among which the SPS technique is probably the most popular, have attracted considerable interest. Spark plasma sintering (SPS) is the process of consolidating powder (metallic or ceramic) constrained in a die (most often graphite) through the application of large amounts of pulsed DC electrical current. Unlike conventional sintering, the SPS process affords rapid heating rates and reduced sintering temperatures that suppress microstructural coarsening. It has been demonstrated that the surface oxides at interparticle contact points can be mitigated by SPS. The SPS method has recently made significant advancements in materials science and materials processing thanks to its capability of fast and efficient densification of a great variety of materials and the suitability of the equipment for conducting solid-state syntheses and syntheses, in which liquid phases can form within limited volumes locally at the contacts between particles. Spark plasma sintering (SPS) has garnered considerable attention for its ability to retain nanocrystalline microstructures a
