Description
Summary:The kinetics of ordering with a reduction of a crystal lattice point symmetry and related transformation-induced elastic strain is considered for the first time. Ordering in YBa sub(2)Cu sub(3)O sub(7- delta ) is specifically discussed. A computer simulation predicts a temporal development of the microstructure through the tweed to the (110) microtwin structure driven by the elastic strain accommodation. The results obtained are quite general in the sense that predicted morphologies are typical for other systems with the point-symmetry reduction where the elastic strain accommodation plays an important role.
