Recrystallization textures of silver electrodeposits

The recrystallization texture of silver electrodeposits obtained from cyani de bath?, containing no additive were investigated. The textures of as-depo sited and recrystallized specimens were determined from thr: pole figures, from which orientation distribution functions and inverse pole figures were calculated. The orientation components of experimentally determined textur es were quantified using the Gauss distribution of ideal orientation compon ents. The (111) + (115)(T), (100) + (221)(I), and (112) + (127)(T), (113) (557)(T), deposition textures changed to the same (100) + (221)(T) recryst allization texture when the specimens were annealed. where subscript T deno tes the twin component of the preceding orientation. The(110) deposition te xtures changed to the (root 310) recrystallization with its twin components . The evolution of recrystallization textures has been explained by the str ain energy release maximization model, in which the absolute maximum intern al stress direction in electrodeposits,sits due to dislocations becomes par allel to the minimum elastic modulus direction of recrystallized grains, wh ereby the strain energy release of the material can be maximized.
