摘要

We have computed the lattice constants, bulk modulus, and total- and partial-density of states of MAX phases Ti₂InC, Zr₂InC and Hf₂InC in the hexagonal P6₃/mmc space group by ab initio calculation. The deviations from the experimental values for lattice constants are below 1.6%. The bulk moduli are computed to be 128 GPa, 113 GPa, and 136 GPa, respectively. The Zr₂InC has the lowest bulk modulus among all MAX phases studied to date, which is related to the weaker covalent interaction between Zr-d and C-s, C-p states.
