Growth and preferred orientations of crystals in tungsten wires

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