Download or read book Martensitic Transformation written by Zenji Nishiyama and published by Elsevier. This book was released on 2012-12-02 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Martensitic Transformation examines martensitic transformation based on the known crystallographical data. Topics covered range from the crystallography of martensite to the transformation temperature and rate of martensite formation. The conditions for martensite formation and stabilization of austenite are also discussed, along with the crystallographic theory of martensitic transformations. Comprised of six chapters, this book begins with an introduction to martensite and martensitic transformation, with emphasis on the basic properties of martensite in steels such as carbon steels. The next two chapters deal with the crystallography of martensite and discuss the martensitic transformation behavior of the second-order transition; lattice imperfections in martensite; and close-packed layer structures of martensites produced from ? phase in noble-metal-base alloys. Thermodynamical problems and kinetics are also analysed, together with conditions for the nucleation of martensite and problems concerning stabilization of austenite. The last chapter discusses the theory of the mechanism underlying martensitic transformation. This monograph will be of interest to metallurgists and materials scientists.

Download or read book Micromechanical Modeling of Size-dependent Crystal Plasticity and Deformation Twinning written by Edgar Husser and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The computational modeling and simulation of the deformation behavior of crystalline materials at the micron scale is the objective of this thesis. Numerous experimental studies have proven that small-scaled metallic probes behave mechanically different from their bulk counterparts, in particular, the yield strength and work hardening behavior is affected in the way that smaller single crystals behave stronger. This characteristic behavior opens up new design possibilities for further improvement of mechanical properties of engineering material systems. In view of high expenses for advanced and complex experimental work along with the inherent testing limitations, numerical methods offer a great option to validate experimental findings, support the development of suitable theories, and extend scientific investigations on a computer-aided basis. A gradient crystal plasticity model is presented in this thesis and applied to selected scientific problems including the mechanical testing of single crystals via simulation of microcompression and microbending using a three-dimensional finite element framework. The model is implemented on an element basis and linked to the commercial finite element software Abaqus via the user subroutine UEL. Two major deformation mechanism are considered by the underlying model. Deformation via crystallographic slip is modeled in a non-local fashion allowing to account for gradient effects. Geometrically necessary dislocation (GND) densities associated with plastic slip gradients are introduced as additional nodal degrees of freedom while the actual plastic slip variables are handled as internal variables. Deformation twinning is accounted for in terms of a simple shear deformation associated with shear and shuffling of atoms. In addition, the twinning-induced reorientation of the crystal lattice is fully considered along with subsequent activation of slip modes within the twinned region. In accordance to the non-local crystal plasticity framework, the gradient of the twin volume fraction is introduced at the nodal level. The actual twin volume fraction is treated as an extended internal variable yielding a coupled system of highly non-linear equations at the local level. The competitive nature between slip deformation and deformation by twinning is addressed by physically motivated interaction relations. The characteristic features of the model are portrayed for a variety of micromechanical problems and in relation to experimental results.

Download or read book Crystal Plasticity Based Formability Analysis of Transformation Induced Plasticity Steels written by Pingcheng Zhang and published by . This book was released on 2018 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis outlines a framework to model to aid the development and utilization of transformation induced plasticity (TRIP) assisted multiphase steels in the automotive industry for light weighting applications. Automakers rely on accurate characterization and prediction of sheet metal formability to implement these materials into the structure successfully. They rely on accurate numerical models for predicting and evaluating sheet formability compared to the costly experimental method. However, predictive modeling of TRIP steel in formability is difficult due to the combination of dislocation and transformation mechanisms occurring during deformation for various strain paths. This research is aimed to provide a tool to quickly and accurately capture the micro and macro mechanical response of TRIP assisted steels, as well as calculating the forming limit diagram used in evaluating formability. This thesis presents a rate-dependent Taylor type elasto-viscoplastic crystal plasticity model with a micro-mechanics based transformation criteria to simulate the mechanical response of TRIP steel. A new stress-based transformation criterion, based on the micromechanics of habit- plane interaction, was developed to initiate transformation. This model inherently captures the triaxiality effect of martensite through the accumulated shear strain on slip systems. Simulations are calibrated and compared to experimental measurements of Duplex Stainless Steel (DSS). Simulations of single crystal and polycrystalline aggregates show that although high Schmid factor habit planes were favourable for transformation, competition exists between the lower Schmid factor dislocation planes that generate higher elastic stress needed for transformation. The calibrated model is then used to predict the forming limit diagram using the Marciniak-Kuczynski approach. The mechanism of transforming from low strength austenite to high strength martensite showed enhanced formability by at least 20% compared to without transformation. This is achieved by the TRIP mechanism suppressing localization at critical moments during deformation. However, the single variant martensite selection scheme had a negligible influence on formability predictions. Through a parametric study of the transformation criteria, formability can be enhanced on the biaxial regime by up to 13% over the baseline DSS material. Conversely, poor control of the transformation parameters could lead to a reduction of 50% in formability. The results highlight the importance of a physics based simulation to utilize TRIP assisted steels fully.
