A review of the literature and discussions with plant operators has been undertaken to establish present knowledge and understanding of the chemistry of the condensates formed on steam turbines and the link to system operation. This has been supplemented by an overview of the effect of test variables on environment assisted cracking. In Section 1, steam turbine operating conditions are describe...

The motivation of the study is the development of a coupled approach able to account for the interaction between environment and plasticity in a polycrystalline material. The paper recalls first the constitutive equations used to describe the behaviour of the grain core and of the grain boundary (GB). The procedure that is applied to generate synthetic polycrystalline aggregates with an explici...

Stress corrosion experiments were performed on unidirectional ECR-glass/polymer composites with the modified polyester, epoxy and vinyl ester resins for the use in high voltage composite insulator applications. Two types of ECR-glass fibers with low and high seed counts were investigated. The stress corrosion tests were performed in nitric acid under four point bending conditions and the resist...

The sensitization and subsequent intergranular corrosion of Al-5.3 wt.% Mg alloy has been shown to be an important factor in stress corrosion cracking of Al-Mg alloys. Understanding sensitization requires the review of grain boundary character on the precipitation process which can assist in developing and designing alloys with improved corrosion resistance. This study shows that the degree of ...
