Abstract
It is shown that an unstable crystal structure in a stress field can be treated as a quantum system of pseudospins. A stimulating strain field gives rise to quantum tunneling of atoms. The latter effect is a physical cause for a coherent behavior of the crystal in a stress-concentrator zone wherein the material undergoes the nonequilibrium structural transformation γ → a highly-excited state → γ under load.
