Abstract

This article presents a model to describe the constitutive behaviour of corrosion-resistant Sandvik steel NanoflexTM [1] during metal forming and hardening. This material is characterised by different phenomena. The material is metastable, which causes strain-induced transformation to take place during metal forming. Depending on the annealing conditions, the material also transforms isothermally [2, 3] (as opposed to a-thermal martensite). This transformation can also take place immediately after forming, as a result of the residual stresses present in the material. The martensite phase of this material can be aged [4]. Results of the various measurements on Sandvik NanoflexTM are shown. The measurements mainly involved tensile tests and upsetting tests, during which both isothermal transformation and strain-induced transformation were measured by inductive sensors[5] and they were afterwards examined. The hardening of the material and the increase in hardness during ageing was also examined. Finally, a constitutive model based on literature and the measurement are presented. This model describes the isothermal, stress-assisted transformation, strain-induced transformation, work hardening and ageing. The model has been set up in such a way that it can be simply implemented in a FEM code
