Elastic properties and phonon conductivities of Ti3Al(C-0.5,N-0.5) and Ti2Al(C-0.5,N-0.5) solid solutions Academic Article uri icon

abstract

  • Herein we compare the lattice parameters, room temperature shear and Youngs moduli, and phonon thermal conductivities of Ti2AlC0.5N0.5 and Ti3Al(C0.5, N0.5)2 solid solutions with those of their end members, namely Ti2AlC, Ti2AlN, Ti3AlC2, and Ti4AlN2.9. In general, the replacement of C by N decreases the unit cell volumes and increases the elastic moduli and phonon thermal conductivities. The increase in the latter two properties, however, is sensitive to the concentrations of defects, most likely vacancies on one or more of the sublattices.
