Rietveld analysis and mechanical properties of in situ formed La-β-Al2O3/Al2O3 composites prepared by sol-gel method
(Elsevier, 2022)
In this work, the crystal evolution of α-Al2O3 composites reinforced with LBA platelets were monitored by XRD Rietveld. In addition, the mechanical properties of totally densified specimens were researched by Vickers ...

Fabrication and creep properties of eutectic-composition Al2O3/YAG/YSZ sintered composites
(Elsevier, 2021-12)
Three-phase alumina/YAG/yttria-stabilized cubic zirconia (YSZ) composites were fabricated by a solid-state reaction route starting from commercial powders of Al2O3, Y2O3 and monoclinic ZrO2. The final phases Al2O3, YAG and ...

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 ...
