摘要

The micro yielding and damage behavior of the austenitic and ferritic phases in duplex stainless steels can affect the strength, deformation and fracture behavior of these materials. A fundamental understanding of the influence of macro loading and microstructure on the micro yielding and damage behavior of the individual phases is therefore important to the material design and development. This paper provides a review on the methods and the investigations that have been performed recently for studying load partitioning, micro yielding and deformation hardening rate in super duplex stainless steels SAF 2507 and SAF 2906 using in-situ diffraction methods such as neutron and X-ray diffraction, micro and nano indentation, and multi-scale material modeling. The micro damage or dislocation slip behavior in these two materials is also discussed.
