We make an attempt to explain brittle propagation of short fatigue cracks in specimens of WT3-1 titanium alloy tested by simultaneous bending and torsion. It is assumed that the fracture process can be affected by hydrogen absorbed from the atmosphere and penetrating to the tips of microcracks in the subsurface layer of the material. Higher concentrations of hydrogen observed near the crack lips located near the specimen surface as compared with the bulk of the specimen confirm the assumption that the effect of hydrogen is responsible for the brittle propagation of short fatigue cracks.
