en Research Paper Research Paper Abstract: Microwave processing is one of the novel methods for combustion synthesis of intermetallic compounds and<br>composites. This method brings about a lot of opportunities for processing of uniquely characterized materials. In this<br>study, the combustion synthesis of TiAl/Al2O3 composite via microwave heating has been investigated by the<br>development of a heat transfer model including a microwave heating source term. The model was tested and verified<br>by experiments available in the literature. Parametric studies were carried out by the model to evaluate the effects of<br>such parameters as input power, sample aspect ratio, and porosity on the rate of process. The results showed that<br>higher input powers and sample volumes, as well as the use of bigger susceptors made the reaction enhanced. It was<br>also shown that a decrease in the porosity and aspect ratio of sample leads to the enhancement of the process.
