✦ Synopsis

The solid solution hardening of stainless steels is studied by using the Labusch-Nabarro relation. Models are evaluated in order to predict the mechanical properties from chemical composition, solution hardening misfit parameters, grain size, ferrite content and product thickness. A data source of six grades of steels is used for the modelling. Both austenitic and duplex stainless steels are covered including more than 1100 batches, which are subjected to multiple regression analyses. The models are compared with earlier studies and can be used as tools in material optimisation.

As other metallic materials, in low-cycle fatigue, duplex stainless steels (DSS) exhibit a cyclic hardening, followed by a cyclic softening, before stabilization of the stress. In order to simulate the cyclic hardening/softening curves in low-cycle fatigue of an austenitic-ferritic or duplex stainle
