This material is widely used in industrial applications and so needs accurate behaviour modeling. Tests have been performed in the temperature range from 25 degrees C to 1020 degrees C and at strain rates between 10(-3) s(-1) and 1 s(-1). This allowed the identification of a multiphase mechanical model coupled with a metallurgical model. The behaviour of each phase is calibrated by solving an inverse problem including a phase transformation model and a mechanical model to simulate tests under thermomechanical loadings. A scale transition rule (beta-rule) is proposed in order to represent the redistribution of local stresses linked to the heterogeneity of plastic strain. Finally this model is applied to two laser assisted processes: direct laser fabrication and laser welding. (C) 2009 Elsevier B.V. All rights reserved.

F.Mariage C.Colin G.Cailletaud article Xiong:2009 Journal of Materials Science 2009 44 2 632-638 In this study, hypoeutectoid Fe-N binary specimens have been prepared by gas nitriding pure iron in austenite domain at 840 A degrees C. The slow cooling of these specimens led to the alpha-ferrite + gamma'-Fe(4)N pearlitic microstructure which is similar to the pearlite in Fe-C binary system. This pearlitic microstructure has been characterized by electron microscopy. The crystal structure of the gamma'-Fe(4)N nitride has been identified by electron microdiffraction and the Nishiyama-Wassermann (N-W) and near Kurdjumov-Sachs (K-S) orientation relationships have been found between the alpha-ferrite and the gamma'-Fe(4)N.
