Abstract

On the example of an alloy VT20 the problem of solid-metal embrittlement of titanium alloys in contact with silver, zinc and cadmium in the solid state was considered. The influence of the contact density of the surface of titanium alloy with metals, temperature and duration of tests, as well as the application of external tensile stresses were investigated. Temperature thresholds and incubation periods of cracking of VT20 alloy in contact with the studied metals were determined. Studies of fractures of titanium samples and analysis of the chemical composition of their surface after testing were carried out.
