Abstract :
The tensile properties were investigated from 1273 to 1973 K for recrystallized pure W and W-1%La2O3. The WLa2O3 showed much higher strength than the pure W, but slightly lower elongation, except at 1273 K where the pure W suffered from intergranular fracture. The excellent mechanical properties of the WLa2O3 are probably the result of the structure, consisting of elongated grains, which resists grain boundary sliding.
