Abstract  

MoSi2 composites with different Si 3N 4(p) and SiC(w) volume contents are prepared by means of wet mixing and heat pressing process. The morphology, grain size, hardness, fracture toughness, bending strength of the MoSi2–Si3N4(p)/SiC(w) composites were investigated by means of scanning electron microscope (SEM), polarizing microscopy, vickers hardness tester, and universal material testing machine in this paper. It is shown that mechanical properties of the prepared composites are much higher than that of MoSi2, and its grain size is finer than that of MoSi2, more over it is declined with the increasing of strengthening phases. MoSi2–20% Si3N4(p)–20% SiC(w) composite has better mechanical properties, and its bending strength and room fracture toughness are 427 MPa and 10.4 MPa·m1/2, respectively. The strengthening mechanism of MoSi2– Si3N4(p)/SiC(w) composites are fine grain strengthening and dispersion strengthening, and the toughening mechanism are fine grain toughening and crack deflection toughening.
