As early as the 1930s, companies were researching the development of duplex grades of steel that were more resistant to cracking and corrosion, but it wasn’t until the 1960s and 1970s when improvement in refining techniques resulted in better product quality, that major progress was made. Since that time, the use of duplex stainless steels […]

SWCNTs and MWCNTs and Genotoxicity Carbon nanotubes (CNTs) are an allotrope of carbon. Since their discovery in 1991 they have been used for a variety of applications including fiber optics, conductive plastics, and molecular electronics, as well as biological and biomedical applications. Their unique properties make them commercially important. They exhibit extraordinary strength and are […]

What is Corrosion Fatigue? Corrosion fatigue is the combined action of fatigue and corrosion. It can produce a failure in fewer cycles and lower loads than if either corrosion or fatigue were acting alone. Of all corrosion failure mechanisms, it is the most difficult to identify especially in the presence of low-frequency loading. At very […]
