The axial compressibility, thermal expansion and elastic anisotropy of Hf 2SC under pressure
Using plane-wave pseudopotential density functional theory and Debye model,
we have studied the axial compressibility, thermal expansion and elastic
anisotropy of Hf2SC at different temperature and pressure. It is found
that the bulk moduli Ba and Bc (along the a and c axes, respectively)
almost linearly increase with pressure and the former is always smaller than
the latter. The ratio of Bc/Ba has a trend of gradual increase as
the pressure increases. We observe that the GrĂĽneisen parameter Îł and
thermal expansion coefficient α decrease when increasing pressure, on the
contrary, the anisotropy, Debye temperature, longitudinal wave velocity and
transverse wave velocity increase with pressure
