Abstract
Thermochemical calculations were carried out for the self-propagating high temperature synthesis (SHS) of MoSi 2 WSi 2 alloys. Adiabatic temperatures and amounts of liquid phase of MoSi 2 and WSi 2 formed were calculated at various initial temperatures for the reactions forming MoSi 2, WSi 2 and their alloys. These alloys were prepared using elemental powders of Mo, W and Si by the thermal explosion mode of SHS. The products were characterized by X-ray diffraction and scanning electron microscopy. The morphologies of the alloys are explained with the help of the thermomechanical calculations.
