Electrochemical investigations regarding the influence of deformation-induced martensite on the corrosion behaviour of austenitic stainless steels

  • Contents of deformation-induced martensite in the lattice structure of austenitic stainless steels lead to an either beneficial or detrimental change of mechanical and magnetic properties depending on the prospective application. Whereas these changes are well-known and investigated widely the influence of deformation-induced martensite on the corrosion behaviour is frequently an issue of scientific discussions. There are opposing opinions that depend on the type of corrosion mechanism being investigated for example regarding pitting corrosion resistance in Chloride containing media. In it is stated that pitting resistance is not influenced by deformationinduced martensite while in it is discussed that more pitting occurs on martensitic structure. The same conflictive opinions appear regarding active dissolution in acidic media or intergranular corrosion. In addition, when having deeper insight into literature it can be concluded that even the type of test method, i. e. dynamic orContents of deformation-induced martensite in the lattice structure of austenitic stainless steels lead to an either beneficial or detrimental change of mechanical and magnetic properties depending on the prospective application.

In addition, when having deeper insight into literature it can be concluded that even the type of test method, i. e. dynamic or static testing, has a big influence on the obtained results concerning the influence of martensite in austenitic stainless steels.zeige mehrzeige weniger
