摘要：

Tensile tests on coarse-grained (~0.3 mm) commercially-pure titanium containing 0, 30, 50, 85, 250 and 525 p.p.m. of hydrogen have been carried out. The tests were performed at -196 °, -78 °, 20 °, 150 ° and 300 °C at a strain rate of ~1.0 × 10-3 sec-1. The hydrogen embrittlement of the titanium, measured in terms of a reduction in both fracture stress and elongation to fracture, was enhanced by increasing hydrogen content and decreasing test temperature. This mechanical behaviour has been correlated to the influence of precipitate morphology and test temperature on the introduction of cracks into the titanium matrix by failure associated with the hydride precipitates. © 1968.
