Abstract:

Tension and tensile fatigue tests of annealed and drawn Ta have been performed in vacuum at high temperature. Relations between tensile strength σ B and fatigue strength for the annealed and the drawn Ta have been studied. The results obtained are as follows:
(1) Relation between σ B and testing temperature T in the range of 1073∼2273 K are approximately given by
