“…It was found that by increased duration, the oxide structure was transformed into complex Sr-containing oxides. Mehrabian [17] shown experimentally how trapped air bubble can result in breakaway oxidation and illustrated this mechanism impeccably. Ozer [18] and Bhagyanathan [19] studied the recycling efficiency of aluminum cans and showed that oxidation during remelting is the key parameter for improved melt cleanliness.…”

“…In addition, introducing booster second phases comprising SiC, TiC, and B 4 C , as reinforcement or sintering aids has been reported to be beneficial for the sinterability and quality enhancement of TiB 2 -based composites 30 – 33 . The incorporation of a suitable second phase may result in the in-situ formation of nanosized phases, which significantly affects the final mechanical properties, especially the fracture toughness and strength 34 – 37 .…”

A carbon-fiber (Cf) doped TiB2–SiC composite was prepared and investigated to determine its densification behavior, micro/nanostructural properties, and mechanical characteristics. TiB2–25 vol% SiC–2 wt% Cf was prepared at 40 MPa and 1800 °C for 7 min using the pulsed electric-current sintering technique, and a relative density of 98.5% was realized. The as-sintered composite was characterized using advanced techniques, e.g., X-ray diffractometry, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, field-emission electron probe micro-analysis, and nanoindentation. The Cf additive could remove the surface oxide layers from the TiB2 and SiC domains, thus transforming them into TiB2 and SiC. According to micro/nanostructural studies, Cf could not retain its initial structure and was eventually converted into graphite nanosheets. In addition, the prepared composite was examined using the nanoindentation technique, and the following results were obtained for the calculated hardness, elastic modulus, and stiffness values: TiB2 > SiC > TiB2/SiC interface.
