Powder-metallurgy fabrication of ZrB2-hardened Zr3Al2intermetallic composites by high-energy ball-milling and reactive spark-plasma sintering
(Elsevier, 2022)
A powder metallurgy route combining high-energy ball-milling (HEBM) of elemental powders and reactive spark-plasma sintering (SPS) is proposed for the controlled fabrication of novel composites based on a Zr-Al intermetallic ...

Evidence of nanograin cluster coalescence in spark plasma sintered α-Al2O3
(Elsevier, 2013)
The aim of this study is to elucidate the coarsening kinetics involved during densification of fine-grained pure α-alumina by spark plasma sintering. Low temperature and short dwell time sintering conditions were used to ...

Improvement of Vickers hardness measurement on SWNT/Al2O3 composites consolidated by spark plasma sintering
(Elsevier, 2014)
Dense alumina composites with different carbon nanotube content were prepared by colloidal processing and consolidated by Spark Plasma Sintering (SPS). Single-wall carbon nanotubes (SWNTs) were distributed at grain boundaries ...

Cation-driven electrical conductivity in Ta-doped orthorhombic zirconia ceramics
(Elsevier, 2021)
This paper is devoted to the study of the electrical conductivity of tantalum-doped zirconia ceramics prepared by spark plasma sintering. In this study, the temperature dependence of conductivity in as-prepared specimens ...
