Synthesis, crystal structure, microstructure and mechanical properties of (Ti_1-xZr_x)₃SiC₂ MAX phase solid solutions

Almost pure (Ti_1-xZr_x)₃SiC₂ MAX phase solid solutions with x ranging up to 0.17 were synthesized at temperatures in the range of 1450–1750 °C with reactive Spark Plasma Sintering (SPS). The zirconium partially replaces the M-element titanium of the Ti₃SiC₂ MAX phase up to x...

Thermo – mechanical properties of SPS produced self-healing thermal barrier coatings containing pure and alloyed MoSi₂ particles

Yttria – partially stabilised zirconia (YPSZ) MoSi₂ composites have been designed to prolong the lifetime of the matrix by self – healing cracks during thermal cycling. The healing reaction at high temperatures is based on the decomposition of MoSi₂, leading to a volumetrically expanding reaction product, which seals the...
