As a basis, we implement a scalar‐valued Gibbs‐energy‐barrier‐based phase‐transformation model making use of statistical physics. In this work, we particularly adopt the model for the simulation of phase‐transformations between an austenitic parent phase and a martensitic tension and compression phase. The incorporation of plasticity phenomena is established by enhancing the Helmholtz free energy functions of the material phases considered, where the plastic driving forces acting in each phase are derived from the overall free energy potential. The coupled model is embedded into a micro‐sphere formulation in order to simulate three‐dimensional boundary value problems—a technique well‐established in the context of computational inelasticity at small strains. It is shown that the model is capable of reflecting experimentally observed behaviour. (© 2011 Wiley‐VCH Verlag GmbH & Co.

Tests in the lowcycle fatigue (LCF) regime were conducted on material that was processed by the equal channel angular extrusion (ECAE) technique along the so called “efficient” route 8E. This route has been shown to result in a homogeneous microstructure with a high fraction of high angle grain boundaries (HAGBs), which are beneficial for a stable CSSR. In addition, the evolution of the microstructure was characterized by means of electron optical techniques, including electron backscattered diffraction, and by X-Ray diffractometry. It was found that the initial texture of specimens cut from the ECAE billet along different orientations with respect to the extrusion direction (ED) has a substantial effect on the CSSR of the UFG IF steel. Furthermore, microscopy results indicated the notable influence of the last ECAE processing step on the evolution of damage in the material.}}, author = {{Niendorf, Thomas and Marten, Thorsten and Maier, Hans J. and Karaman, Ibrahim}}, issn = {{1662-9752}}, journal = {{Materials Science Forum}}, pages = {{864--869}}, title = {{{The Effect of Texture on the Fatigue Properties of Ultrafine-Grained Interstitial-Free Steel}}}, doi = {{10.4028/www.scientific.net/msf.584-586.864}}, volume = {{584-586}}, year = {{2008}}, } @inproceedings{33878, author = {{Tröster, Thomas and Rostek, W. and Böke, J. and Erhardt, R.}}, booktitle = {{Ein wesentlicher Beitrag zur Klimadebatte}}, location = {{Berlin}}, title = {{{Einsatz von Simulationswerkzeugen in der Entwicklungskette von ultrahochfesten warmgeformten Strukturkomponenten im Fahrzeugleichtbau}}}, volume = {{675}}, year = {{2008}}, }
