Funds are provided for the continuation of the effort on high                   resolution transmission electron microscopy study of phase                      transitions and solid state reactions in modulated structures.                  Major emphasis of the study is directed toward understanding the                                                                                                mechanism of discommensuration process and the kinetics of the                  incommensurate-commensurate phase transitions which occur in                    modulated structures, in particular those formed by the CDW                     (charge density wave) formation in transition metal                             dichalcogenides such as tantalum selenide and tantalum sulfide                  and in long period superlattice in alloys such as silver-                       magnesium.  Mechanisms of boundary motion in forming modulated                  structures of different periods which accompanies the                           commensuration process will also be investigated.
