“…Researches in recent years revealed that adding multi-scale particles into brittle matrix was an effective method to enhance strength and toughness of Al 2 O 3 -based ceramics. Compared to the Al 2 O 3 -based composite reinforced with only single-scale particle, the flexural strength and fracture toughness of Al 2 O 3 -based composites synergistically strengthened and toughened with micro-sized and nano-sized particles are improved about 4~44% and 33~62%, respectively [6][7][8][9].…”

“…Aluminium oxide is one of the most used materials in the industry because of its superior hardness, chemical inertness and electrical/thermal insulation properties [4]. Alumina is used in ceramic, glass, refractory industry, grinder material production, primary aluminium production, transparent armour production and ceramic cutting production [5][6][7].…”

Alumina powders containing varying ratios of B4C were mixed in a V-type mixer for 30 min with 35 cycle/min to obtain a homogeneous mixture. Six different chemical compositions were prepared and sintered at 1600• C for 20 min using an Ultra-High-Frequency Induction Heated System. The samples were cooled by air. The density, surface roughness, hardness and microstructure of samples were investigated. The results showed that when the amount of B4C increased, the values of hardness increased and the values of surface roughness decreased.K e y w o r d s : alumina, boron carbide, sintering, induction, composite

“…Both the domestic and foreign researches indicate [3][4][5][6][7][8][9] that the addition of TiC and TiN particles into Al 2 O 3 matrix can improve the flexural strength and the fracture toughness. Titanium carbide (TiC) possesses high hardness (32 GPa) and high melting point (3140°C).…”

“…Titanium carbide (TiC) possesses high hardness (32 GPa) and high melting point (3140°C). TiC particles can stop the original crack from growing as a result of pinning effects [3,4]; therefore, the strength, hardness, thermal shock stabilities and thermal conductivity of alumina ceramics can be increased. The toughening mechanism is revealed by the crack deflection and bridging observed in the microstructure of Al 2 O 3 -TiC composites [5].…”

Al 2 O 3 -TiN-TiC ceramic materials with different Ni content were fabricated by hot-pressing technique. Mechanical properties such as flexural strength, Vickers hardness and fracture toughness were obtained by three-point-bending test and Vickers indentation method. The microstructures of the sintered body were observed by scanning electron microscopy. The effects of Ni content on the microstructures and the mechanical properties of Al 2 O 3 -TiN-TiC ceramic materials were investigated. The results indicated that the addition of Ni could change the topography of the microstructures which displayed various core-shell structures. Moreover, the fracture mode changed with the increment of Ni content. When the addition of Ni was 3 vol%, the flexural strength and fracture toughness were the greatest and the improvement could be explained by the unique microstructures of sintered bodies.
