Microstructure And Mechanical Properties

TiB2-(W,Ti)C composites with (Ni,Mo) as sintering additive have been fabricated by hot-pressing technique, and the microstructure and mechanical properties of the composites have been investigated. (Ni,Mo) promotes grain growth of the composites. In the case of 7vol.% (Ni,Mo), the grain size decreases consistently with an increase in the content of (W,Ti)C. When the proper content of (W,Ti)C is added to TiB2 composites, the growth of matrix grains is inhibited and the mechanical properties of the composites are improved. The best mechanical properties of the composites are 1084.13MPa for three-point flexural strength, 7.80MPa•m 1/2 for fracture toughness and 17.92GPa for Vickers hardness.

Microstructure And Mechanical Properties

Sialon matrix composites were prepared from a reaction mixture of Si3N4, Al2O3 and Y2O3 powders and reinforced with Fe3Al obtained by mechanical alloying, which also can assist sintering at a low temperature. The specimens were sintered by two–step hot pressing and then characterized for phase composition, microstructure and mechanical properties. The effect of the Fe3Al variables on the mechanical properties was studied.
