Effect of hydrogen on susceptibility of alloy VT5L to delayed brittle fracture

Conclusions

  1. 1.

    Raising the hydrogen concentration in alloy VT5L to more than 0.014% greatly increases its susceptibility to delayed brittle fracture. At σ=40 kg/mm2 delayed brittle fracture does not occur in the alloy with 0.017–0.05% H in the course of tests for 400 days.

  2. 2.

    The development of brittle fracture is affected mainly by the directional diffusion of hydrogen under the influence of stress.
