Optimization of the synthesis parameters to obtain Mo2TiAlC2 MAX phase

Abstract

Transition metal carbides (TMC’s) emerged as an important class of materials for wide range of industrial applications. The wide applicability of a TMC’s is limited due to their brittle nature. To enhance the ductility of TMC’s, a metallic character has to be introduced. This lead to development of novel class of materials known as MAX phases. These are nano-laminated ternary compounds possess remarkable combination of both metallic and ceramic properties such as high stiffness, high electrical conductivity, thermally stable and low thermal coefficients. Herein, the synthesis of the Mo2TiAlC2 MAX phase via conventional sintering method is investigated. The sintering parameters are optimized to obtain Mo2TiAlC2 MAX phase. The role of titanium carbide precursor for the synthesis of Mo2TiAlC2 MAX phase is studied. The structural properties of the prepared samples are studied through X-Ray Diffraction Technique. Also, the morphology of the prepared sample is studied via Scanning Electron Microscopy (SEM).
