摘要：

Elastic properties and thermal-phonon scattering are investigated in Al2O3 + 0.3% MgO ceramics and cermets of different porosities based on them. The cermets, reinforced with a metallic frame of the steel 12X18H9T, are obtained by dry compaction followed by sintering. It is shown that the elastic moduli of cermets are determined by their porosity and that the grain boundaries can be investigated in detail by a nonequilibrium-phonon propagation method.
