英文摘要 | The formation and migration energies of the mono-vacancy in M(3)AC(2) have been investigated using first-principles calculations. The results have shown that M element vacancy formation is the most energetically difficult in M(3)AC(2). The A atomic layer is the most active one. It was also found that the energies of mono-vacancy formation and migration in Ti3AlC2 are higher than that in Ti3SiC2 and Ti3GeC2. Moreover, our calculation of the density of state confirms the conclusion that Ti3AlC2 is the most stable in the selected M(3)AC(2) materials under high-temperature or irradiation environment conditions. These results could provide theoretical insights for the experimental results that Ti3AlC2 has a better radiation resistance than Ti3SiC2 and Ti3GeC2. |
