Investigating the effect of hydrogen on the mechanical properties of materials
Entity:
Evaluation of the effect of hydrogen on the mechanical properties of metallic and non-metallic materials.
Obtaining fracture maps as a function of hydrogen content to determine the threshold or critical hydrogen content that reduces mechanical properties.
Evaluation of the loss of properties when the material contains different concentrations of hydrogen introduced by electrochemical techniques. The loss of properties due to the effect of hydrogen is evaluated with the following mechanical tests: four point bending test (4PBT), slow strain rate test (SSRT), step load test (SLT), constant load test (CLT), U-bend and cracking resistance.
Evaluation of the effect of hydrogen gas on metallic and non-metallic materials with static tests in hydrogen atmospheres at 100 bar. Subsequently, the loss of mechanical properties is evaluated.
Challenges met
- It facilitates evaluation of the effect of hydrogen on the mechanical properties of materials.
- It classifies materials according to their susceptibility to hydrogen embrittlement, allowing a better selection of materials.
Scope of application
- High strength steels for the automotive, infrastructure and naval transport sectors.
- Carbon steels, aluminium, titanium and other metallic and non-metallic materials.
