EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

A superduplex stainless steel grade has been produced by powder metallurgy and laser metal deposition. The proper heat treatments have been performed to obtain approximately equal volume fraction of austenite and ferrite phases and avoid precipitation of detrimental phases, as chromium nitrides or sigma phase. The corrosion behaviour of the superduplex stainless steel samples has been studied...

Engineering structures are known to withstand significant applied loads, in order to respect static requirements. With time, the environmental sustainability became an important aspect for construction systems. Therefore, the durability issues acquired an increased attention. Materials and systems are subjected to atmospheric degradation. Geographic location, orientation, degree of exposition,...
