Book excerpt: This compilation opens with a section discussing the key interactions required to successfully friction stir weld carbon steels. Friction stir welding is a relatively recent development, predominantly technologically established using aluminum, where the lower melting point of the material greatly aided the process. Next, corrosion models of carbon steel in aqueous solution are reviewed under atmospheric and oxygen depleted environments by focusing on the cathodic reaction and the corrosion film formed on carbon steel as a function of pH and anions. In conclusion, the temperature relation of interlamellar spacing of pearlite with supercooling in carbon steels, based on a previously theoretically foundation, has been determined by the pearlite and bainite phase volumes in alloy steels from the degree of supercooling.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing to the complexity of the mechanical response of Dual Phase (DP) steels, steel makers rely largely on experiments and trial-and-error approaches to develop new lines with higher strength and ductility in order to enable light weighting of automotive parts. Crucially, the flow and failure behaviors are intimately linked to the morphology of the microstructure. This thesis focuses on developing two approaches that use morphological features to predict the flow and failure behavior of DP Steels. In the local field approach, realistic microstructures are obtained through electron microscopy and used to construct a composite phase finite element model which is then subjected to uni-axial deformation. The second approach exploits phenomenological models to connect the deformation and failure at the microscopic level to the average mechanical response. Using basic microstructural features and flow behavior of the ferrite and martensite phases, the flow and failure behavior of DP Steels is estimated.

Available in PDF, EPUB and Kindle. Book excerpt: Dual-phase (DP) steel has been developed by automotive industry for the purpose of weight reduction, improvement in safety performance and fuel efficiency. Usually, DP steel contains hard martensite islands embedded in a soft ferrite matrix. Synergy between these two phases with the inhomogeneous microstructure exhibits excellent mechanical properties. The mechanical properties (plasticity and damage behaviors) of DP steel are mostly derived from its microstructure, e.g., volume fraction, size, distribution and morphology of each constituent phase. Micromechanical approaches are vastly applied to predict plasticity and other mechanical properties of DP steel under various loading scenarios. In this work, micromechanical modelling of DP steel has been performed using real or artificial microstructures. A real microstructure is obtained from metallographic image, while an artificial microstructure generator with an enhanced phase assignment algorithm based on material topology optimization is proposed to investigate the mechanical properties. In this artificial generator, phase assignment process is performed on a modified Voronoï tessellation to achieve the tailored representative volume element (RVE) with a good convergence. The proposed method also includes a proper orthogonal decomposition (POD) reduction of flow curves (snapshots), which are computed using the asymptotic extension homogenization (AEH) scheme, to identify the optimal controlling parameters for DP steel. This numerical method is verified using DP590 and DP980 steels that indicate a good agreement with the flow stress from measurements and RVE prediction based on real microstructures. Predictions of plastic strain patterns including shear bands using the artificial microstructure closely resemble the actual mechanical behavior under similar loading conditions. Moreover, an interpolation has been adopted to obtain a correlation between these controlling parameters based on the identification for various DP steels. Additionally, a bi-level reduced surrogate model is developed and presented to identify the material parameters of the Mohr-Coulomb (MMC) fracture criterion. Using this method, the identification process becomes feasible with a limited number of experimental tests. The method combines local critical elements associated with global models. The surrogate model of fracture strain constructed using the diffuse approximation and the local elements, reduced the computational cost for searching material parameters. Global fracture simulations are performed to update the target fracture strain and to compute the corresponding failure onset displacement. Convincing results are obtained via successive application of design of experiment (DOE) and enhanced design space transformation algorithms. The proposed identification protocol is validated with DP590 steel. Robustness of the method is confirmed with different initial values. These numerical investigations provide new direction for multiscale simulations of the plasticity and damage behaviors of DP steel. Moreover, they efficiently contribute to bridge the gap between scientific research and engineering application of heterogeneous materials.
