Computer simulation is used to consider the possibility of creation of microcomposite technical ceramics with a high transcrystalline mobility and to show that allowance for the exchange interactions of atoms through nonequilibrium electrostatic fields causes formation of self-organized mesoscopic (SM) blocks, which provide microplasticity and relaxation of strain at lower temperatures. The simulation results agree with the yield stria observed in mechanical compression tests of Al2O3 specimens obtained from sol-gel solutions. It is shown that the yield stria are directly connected with the sizes of the SM blocks. The high mobility of SM blocks also promotes a decrease in the temperature of the gel → Al2O3 transformation.
