Texture evolution and basic thermal–mechanical properties of pure tungsten under various rolling reductions

Abstract Basic thermal–mechanical properties and texture evolution of pure tungsten with various rolling reductions were characterized. The 60% rolled tungsten exhibited the highest thermal conductivity and the best Charpy impact performance, which can be attributed to its few pores and cracks simultaneously. Furthermore, full recrystallization was achieved on the rolled tungsten with 60% and 90% reduction after annealing at 2073 K for 2 h. More importantly, the 40%, 60%, 90% rolled tungsten displayed more γ fiber texture while 80% rolled tungsten exhibited more θ fiber texture and Goss texture. The rolled pure tungsten with 80% reduction may exhibit the best irradiation resistance.
