| Abstract |
| Nanopowders of Mo, Ti and Si were made by high-energy ball milling. A dense nanostructured (Ti,Mo)Si2 compound was sintered by the pulsed current activated combustion method within two minutes from mechanically activated powder of Mo, Ti and Si. A highly dense (Mo,Ti)Si2 compound was produced under simultaneous application of 80 MPa pressure and a pulsed current. The mechanical properties and micorostructure were investigated. The hardness and fracture toughness of the (Mo,Ti)Si2 were 1030 kg/mm2 and 4.9 MPa·m1/2, respectively. The mechanical properties were higher than monolithic TiSi2. |
