Abstract
It is not so easy to produce iron single crystals which are oriented principal crystallographic axes by using only the recrystallization method. We have found, however, an easy producing method which uses the kernels of single crystals having oriented, principal crystallographic axes. In this method, it is necessary that specimens (99.97% Fe) are carefully annealed in a moist hydrogen stream untilthey nearly lose the cold rolling texture. It must be also needed that the surfaces of the specimens and crystal kernels are as clear as possible, avoiding the etching of the surfaces.
