摘要：
Theoretical prediction of delta ferrite content in cast duplex stainless steels (DSS), and its practical verification, is highly important for mechanical properties, weldability and corrosion resistance of these alloys. Analytical approaches as well as microstructural examinations of castings with wall thickness of 30-120 mm have been performed. Factors that influence the predictions, such as chemical composition, especially higher nitrogen contents and effect of cooling rate, are discussed and suggestions for further researches are given.
