Behaviour of ODS 12Cr steel under thermal treatment at micro and macro level: A positron annihilation and Vickers hardness study

The behaviour of ODS 12Cr steel under thermal treatment is studied in this report at micro and macro level. ODS 12Cr steel is always in the ferrite phase and has a melting point at 1500 ºC. Before studying,<br/>the retrieved samples were metallographically prepared in four steps: mounting, grinding, mechanically polishing and electrolytically...

Concept Design of Steel Bottom Founded Support Structures for Offshore Wind Turbines

To meet growing energy demands wind energy has become an important source of energy. In the last decade wind turbines have been installed offshore to accommodate even more wind power. The offshore wind resource is of a better quality, resulting in higher electricity output. On the other hand, the costs of constructing and installing support...
