Abstract
Nanosized MoSi2 and Si3N4 powders were synthesized from Mo2N and Si powders by high-energy ball milling. A dense nanocrystalline MoSi2–Si3N4 composite was consolidated using the pulsed current-activated sintering (PCAS) method within 3 min period from the mechanically activated MoSi2 and Si3N4 powders. A highly dense MoSi2–Si3N4 composite, with relative density of up to 97%, was produced under the simultaneous application of 80 MPa pressure and 2800 A pulsed current. The mean grain size, hardness, and fracture toughness of the composite were investigated.
