The microstructure and mechanical properties of sintered samples were studied. The results showed that the samples reached full density under the sintering condition of 2000 degrees C and 30MPa. For monolithic B(4)C, the highest hardness of 36.7Gpa, and fracture toughness of 7.11MPa m(1/2) were obtained. In B(4)C -10%SiC composite, the highest flexural strength of nearly 700MPa was measured. The influence mechanism of SiC addition on the mechanical properties of composites was discussed. 发表时间:2010-01-01
