Combustion synthesis of a complex composite based on MoSi[sub 2]
- Defense Metallurgical Research Lab., Hyderabad (India). Combustion Synthesis Group
Self-propagating High-temperature Synthesis (SHS), also known as combustion synthesis, is gaining importance as a technique for producing powders and near net shape components of metals, intermetallics, ceramics and their composites. The agglomeration of reinforcement particles and their non-uniform distribution, which are often attributed to the poor strength of MoSi[sub 2] composites can be avoided in this process. SHS is capable of producing composites with a homogeneous distribution of fine reinforcements in a single step. MoSi[sub 2] has been produced by SHS earlier. The authors have reported the combustion synthesis of MoSi[sub 2]-SiC composites and MoSi[sub 2]-WSi[sub 2] alloys. In this paper, combustion synthesis of a complex composite, namely (Mo,W)Si[sub 2]-SiC, starting from elemental powders by the thermal explosion mode is reported. In the thermal explosion mode of SHS, a volumetric reaction occurs in the reactant compact when it is rapidly heated to the ignition temperature.
