摘要: Abstract This research explores the sintering behavior and microstructure of ZrB2-based materials containing graphene nano-platelets (GNPs) SiC whiskers (SiCw). Spark plasma (SPS) process at 1900 °C was implemented to sinter specimen, leading a composite with 100% relative density. High-resolution transmission electron microscopy (HRTEM), field emission scanning (FESEM), X-ray photoelectron spectroscopy (XPS), emission-electron probe microanalyzer (FE-EPMA), high-resolution diffractometry (HRXRD) were employed study SPSed sample, along thermodynamics predictions. According HRXRD result microstructural observations, non-reactive, which endorsed XPS analysis. Furthermore, presented beneficial role for eradicating oxide impurities in sample during sintering. Such reduced original phases ZrB2, contributing porosity removal. Nanostructural investigations revealed formation ultrathin amorphous interfaces (~10 nm) between ZrB2/graphene phases, disordered atomic planes platelets, dislocations ZrB2 grains. One reason generating crystalline defects found out be mismatches amongst elastic properties available compounds system.
