Corrosion creep of metals

Abstract

Creep behavior of some metals (pure polycrystalline magnesium, die-cast Mg and Al alloys and stainless steel 304) assisted by anodic dissolution in aqueous solutions, which we have called "corrosion creep" (CC), was investigated. The effect of environment on the creep behavior of magnesium and steel is mainly connected with plasticization of metal assisted by chemical reactions and mechanically enhanced anodic dissolution of metal. Anodized Mg-alloys reveal a significantly longer creep life in comparison with uncoated die-cast alloys. © 2008 IOP Publishing Ltd.
