Early stages of the recrystallization texture formation in {112}< 111 > - Oriented silver single crystals
The microtextural changes occurring during recrystallization in high purity silver single crystals with C(112)[11 (1) over bar] initial orientation, deformed by channel die compression, have been studied in detail. The obtained results indicate the great importance of the simple relation of 25-35degrees <111> type, which is observed most frequently at the early stages of the recrystallization process, between isolated nuclei of uniform orientation and one from the two as-deformed components identified within shear bands. Any twin relations between the deformed and the recrystallized phase were not observed. Accordingly, the recrystallization twinning might be regarded only as a secondary mechanism, which is responsible for the growth of the recrystallized phase. The authors try, from the crystallographic point of view, to systematise the validity of the processes operating at the very early stages of the primary recrystallization of fee metals, and to show the way in which the rotation axes were chosen.
