In recrystallized wires of doped tungsten, large crystals have their [421] or [531] axis parallel to the wire axis and small ones tend to keep the original deformation texture [110]. It can be shown that, assuming glide both along 〈111〉 and along 〈100〉 in the tungsten crystals during drawing, the majority of the crystals attain a [110] texture. However some crystals which have an orientation near [531] deform on one glide system only. Therefore, during the last stages of drawing, they will tend to turn with respect to neighbouring crystals having a [110] texture. The presence of a dope inhibits the growth of most of the crystals, but least so that of the [531] crystals, as these will have undergone considerable grain boundary slip, resulting in crumbling of the dope skins. Less dope results in more smaller crystals, less of which have [531] orientation. The nature of the fragmentation which was already found in the large crystals, can be explained on the assumption of tubes or strings of contaminations with blocks and leaks at random places.
