Microstructure oxidation resistance relationship in Ti3AlC2 MAX Phase

Spark Plasma Sintering and Hot Isostatic Pressing were used to synthesize coarse-grained and fine-grained Ti3AlC2 specimens. Moreover, Spark Plasma Sintering processing parameters were modified to vary the TiC, Al2O3, and TixAly impurity and porosity in the fine-grained samples. The influence of the Ti3AlC2 microstructure on the oxidation resistance was assessed. It is demonstrated that the grain size can drastically modify the oxidation resistance. The higher density of grain boundaries in fine
