Neutron Diffraction Study of Annealing Textures in Drawn Body-Centered-Cubic Metals

Abstract

The annealing textures of cold-drawn molybdenum, iron, and an iron base alloy containing 14 pet Al were investigated as a function of annealing temperature by using neutron diffraction techniques. Upon recrystallization, the [110] deformation texture was retained in all cases, and the texture became progressively sharper with increasing annealing temperature. At high temperatures, however, in the case of molybdenum, a new texture appeared. An anomalous diffraction effect was observed for iron; certain (110) plane orientations yielded more integrated intensity than others. Consideration of the problem showed a magnetostrictive effect to be improbable, and a hypothesis concerning the preferred distribution of grains deviating from the ideal [110] orientation is proposed.
