Cel
The objective of the MADS project is to identify the parameters involved in the changes of material properties in deep sea environments. Experiments are carried out on selected materials in high pressure tanks (simulation tests), and laboratory analyses are performed.
The parameters involved in the change of properties in a deep sea environment are identified and simulation tests in a high pressure tank have been carried out in order to test the behaviour of materials used for apparatus design in order to account for the effects of the true environments. The project partners combined unique test facilities and high scientific and technical skills in the field of materials behaviour in a deep sea environment. The first results show that hydrostatic pressure does not affect the corrosion resistance of high grade stainless steels and anodized aluminium alloys. The composite material is not significantly affected by pressure, either. However, high strength steels are more sensisitive to stress corrosion cracking and hydrogen embrittlement under hydrostatic pressure.
The tested materials are mainly metallic alloys (stainless steel, High Strength Low Alloys steels, aluminium alloy, etc), and composite materials. The tested properties are corrosion, stress corrosion, fatigue corrosion behaviour of metallic alloys and composite materials aging (changes of physico-chemical and mechanical properties).
A database on "Materials behaviour in deep sea environment" will be set up to enable results to be communicated efficiently to the scientific and technical community.
