Crystal plasticity finite element study on the formation of Goss-oriented deformation inhomogeneous regions in electrical steels
Abstract
For electrical steels, the volume fraction and distribution of the residual Goss-oriented regions after cold rolling is critical in controlling the Goss texture during subsequent annealing treatment. The heterogeneous distribution of Goss-oriented regions and its evolution is not quantitatively understood and many simulation methods are lack of microstructure information. A full field crystal plasticity finite element method was employed to estimate the microstructure evolution during rolling for a Goss-oriented grain and two setups of bicrystals composing of \((111)[\overline{1 }\overline{1 }2]\) and (110)[001] orientations respectively. The simulation results indicate that the possibility of Goss-oriented grains remaining within microbands depended on the intensity of the two symmetrical \((111)[\overline{1 }\overline{1 }2]\) and \((111)[1\overline{2 }1]\) orientations, and the higher the \((111)[\overline{1 }\overline{1 }2]\)-oriented intensity was, the more residual Goss-oriented regions as microbands were. The \((111)[\overline{1 }\overline{1 }2]\) component intensity was lower and its volume fraction was less under the additional displacement gradient component L13, so that the Goss orientation remained only on the upper and lower surfaces of the rolled sheet in the Goss-oriented quasi-single crystal model. There are the residual Goss-oriented regions as microbands in both groups of bicrystals. When the Goss-oriented grain in the upper part, the intensity of the \((111)[\overline{1 }\overline{1 }2]\) component is higher, and the microbands distribution characteristics of residual Goss-oriented regions are more obvious.
期刊介绍:
The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material.
The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations.
All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.
