Fabrication and Mechanical Properties of Sm_2O_3 Doped CeO_2 Reinforced Ti_3AlC_2 Nano Composite

摘要

The fabrication process of Sm_2O_3 doped CeO_2 reinforced Ti_3AlC_2 nano composites including the nano particle dispersion process by a hetero-coagulation process was developed using in-situ synthesis and densification process of Ti_3AlC_2. The effects of Sm_2O_2 doped CeO_2 nano particles on mechanical properties of Ti_3AlC_2 were investigated. It was found that the presence of 20SDC nano particles in Ti_3AlC_2 was very effective to improve the mechanical properties of Ti_3AlC_2 without spoiling the unique characteristics of Ti_3AlC_2 ternary carbide.
