Five kinds of ceramics were used to evaluate the bending strength under three-point bending. The bending test was carried out at room temperature. The crack-healing behavior and the bending strength of the crack-healed specimens were investigated from room temperature to 1723 K. The bending strength

A water-quenching technique was adopted to evaluate the thermal shock behavior of as-sintered and pre-oxidation Zr 2 Al 4 C 5 -20 vol.%SiC composites in an air atmosphere. The strength retention of the two kinds of composites was measured after varying temperature (DTc) up to 800 Β°C. As-sintered Zr
A detailed investigation is carried out into the influences of the lanthanum oxide (La 2 O 3 ) addition upon the microstructural characteristics and the mechanical properties of the WC-MgO composite bulk prepared by hot-pressing sintering. The results indicate that due to the unique properties of ra
A composite consisting of 30 vol.% MoSi 2 particles in SiC matrix was prepared by liquid phase sintering carried out with the aid of small additions of Al 2 O 3 and Y 2 O 3 and then submitted to dry sliding tests using alumina as the counterfacing body under different conditions of applied load (15,
The machinability of ceramic materials can be improved by the addition of hexagonalβBN. Si~3~N~4~/hβBN composites are suitable as rotor seals for gas turbine engines in the ranges 1000Β°Cβ1300Β°C. Oxidation resistance and strength retention can be improved by the addition of MoSi~2~ up to 1500Β°C. Stre
