Abstract
In this paper the samples based on MoSi2 in Mo-Si-Al triple system were produced. Their densification was studied without using complementary methods and external pressure during synthesis via SHS method. Initially, raw materials (Mo-Si-A) were weighted and mixed together corresponding to Mo (Si 1-x, Alx) 2 with 0.2≤X≤0.5. Mixed powders were pressed by a uniaxial pressing. Then the obtained pellets were preheat and synthesized in combustion reactor. Finally, the parameters affected the samples properties such as percentage of Si substitution with Al, particle size of Si powder, pressing pressure; preheating process and ignition temperature were optimized. The results show that the final densities of synthesized samples were up to 90% TD and their microstructure were uniform.
