Secondary recrystallization of pure molybdenum wires

摘要: Abstract The secondary recrystallization of drawn pure Mo wires has been studied; a particular attention paid on the effect temperature gradients in annealing process. recrystallized grains being very elongated along wire axis have obtained by moderate gradient furnace at about 2000°C. Orientations are mainly 〈023〉 or 〈135〉, while 〈011〉 oriented less frequently observed. In contrast, primary texture consists main component and 〈023〉-〈012〉 sub-component; many large grain sizes. observed discrepancy orientation between is explained terms difference boundary mobilities which depend character boundaries.
