Consolidation and mechanical properties of nanostructured MoSi2 from mechanically reacted powder by high-frequency induction-heated sintering

Abstract

Dense nanostructured MoSi2 was sintered from a mechanically synthesized powder of MoSi2 within 1 min using a high-frequency induction heating method. MoSi2 with a relative density of up to 97% was produced by the simultaneous application of a 60 MPa pressure and an induced current. The average grain size of the MoSi2 sample was approximately 100 nm. The hardness and fracture toughness of the sample was 1203 kg/mm(2) and 4.2 MPa m(1/2), respectively. (C) 2010 Elsevier B.V.
