Abstract:

The formation process of (110)[001] recrystallization texture, i.e. Goss texture, in a cold rolled Fe-3%Si alloy sheet was studied by electron and optical microscopic observations.
In the cold rolled state, the (110)[001] component was found as a very weak volume element in the (111)[1 21] matrix. In the early stages of recrystallization where the recrystallized grains occupied a small fraction of the whole volume of the specimen, (110)[001] grains appeared first and then grew into (111)[1 21] deformed crystals, resulting in forming colonies of grains with Goss orientation. The (111)[1 21] component was scarcely found as a recrystallized grain.
The fact that the process was limited within the above matrix region is very similar to that of the cube texture observed in fcc metals.
Then, the (110)[001] grains coarsened without any remarkable increase of the component in number before consuming the matrix grains of other than the (111)[1 21] orientation. During the process, the (110)[001] grains were supposed to compete each other in a colony.
The development of Goss texture might be interpreted by the configuration and distribution of the (110)[001] component in the cold rolled state together with the impurity effect on grain growth.
