Abstract :
Tensile properties have been investigated at 1273–1973 K in rolled and annealed pure W and W-La2O3 sheets. The as-rolled W-La2O3 showed almost the same strength as the as-rolled pure W. On the other hand, the annealed W-La2O3 exhibited higher strength than the annealed pure W. The higher strength of the annealed W-La2O3 is attributed not only to the dislocation-particle interaction but also to the substructure which is stabilized by the La2O3 particles.
