Download or read book Atomic scale Investigation of Deformation Mechanisms in Concentrated Alloys written by Mulaine Shih and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical behavior of crystalline materials is determined by crystal defects such as dislocations. Understanding the response of defects to forces is thus crucial to improve mechanical properties and to better design and engineer advanced structural materials. Motivated by metastable high entropy alloys (HEAs), we first study the dislocation behavior in a class of metastable fcc alloys. Transitioning from fcc to hcp stable phases in these alloys corresponds to a change from positive to negative average stacking fault energy (SFE). We perform Molecular Dynamics (MD) simulations, and use random NiCo alloys as the model metastable fcc alloy system. We show that the splitting distance between Shockley partial dislocations can remain finite even in a negative average SFE alloy, at finite temperatures. By investigating the effect of average versus “local” SFE on the dislocation stability, and examining the decorrelation force to break the two partial dislocations from equilibrium in these alloys, we are able to piece the puzzle together. We show that in concentrated alloys, the major resisting force is caused by the interaction of dislocations with local solute environments acting on partial dislocations. Next, we present our effort to predict the stress state of atomic-scale defects in experimental observations, captured by high resolution transmission electron microscopy (TEM) images. We propose a new method utilizing the continuum J-integral concept to compute the forces at atomic-scale. The new method is applied to example atomistic simulations of dislocation interactions, and results are validated with its theoretical Peach-Koehler force. Moreover, we investigate the potential origin of preferential deformation at thin deformation twins in CrCoNi alloys under cyclic loading. Assisted from atomistic simulations, we examine the local stress field at the twin boundary with free surfaces. Pure Cu was chosen as our model system for its chemical simplicity and having a similar anisotropy ratio to CrCoNi alloys. We demonstrate the effect of twin size on the strain localization. The high elastic anisotropy induces local stress concentration, which served as a crack initiation site under cyclic loading. We then extend the crack initiation model proposed by Neumann and Tonnessen to discuss the behavior in CrCoNi alloys. In summary, this thesis interrogates the possible deformation mechanisms in concentrated alloys and provides fundamental understanding of the dislocation behavior and offers insight for future alloy developments and applications.

Available in PDF, EPUB and Kindle. Book excerpt: Using a totally new approach, this groundbreaking book establishesthe logical connections between metallurgy, materials modeling, andnumerical applications. In recognition of the fact that classicalmethods are inadequate when time effects are present, or whencertain types of multiaxial loads are applied, the new, physicallybased state variable method has evolved to meet these needs.Inelastic Deformation of Metals is the first comprehensivepresentation of this new technology in book form. It developsphysically based, numerically efficient, and accurate methods forpredicting the inelastic response of metals under a variety ofloading and environmental conditions. More specifically, Inelastic Deformation of Metals: * Demonstrates how to use the metallurgical information to developmaterial models for structural simulations and low cyclic fatiguepredictions. It presents the key features of classical and statevariable modeling, describes the different types of models andtheir attributes, and provides methods for developing models forspecial situations. This book's innovative approach covers such newtopics as multiaxial loading, thermomechanical loading, and singlecrystal superalloys. * Provides comparisons between data and theory to help the readermake meaningful judgments about the value and accuracy of aparticular model and to instill an understanding of how metalsrespond in real service environments. * Analyzes the numerical methods associated with nonlinearconstitutive modeling, including time independent, time dependentnumerical procedures, time integration schemes, inversiontechniques, and sub-incrementing. Inelastic Deformation of Metals is designed to give theprofessional engineer and advanced student new and expandedknowledge of metals and modeling that will lead to more accuratejudgments and more efficient designs. In contrast to existing plasticity books, which discuss few if anycorrelations between data and models, this breakthrough volumeshows engineers and advanced students how materials and modelsactually do behave in real service environments. As greater demandsare placed on technology, the need for more meaningful judgmentsand more efficient designs increases dramatically. Incorporatingthe state variable approach, Inelastic Deformation of Metals: * Provides an overview of a wide variety of metal responsecharacteristics for rate dependent and rate independent loadingconditions * Shows the correlations between the mechanical response propertiesand the deformation mechanisms, and describes how to use thisinformation in constitutive modeling * Presents different modeling options and discusses the usefulnessand limitations of each modeling approach, with material parametersfor each model * Offers numerous examples of material response and correlationwith model predictions for many alloys * Shows how to implement nonlinear material models in stand-aloneconstitutive model codes and finite element codes An innovative, comprehensive, and essential book, InelasticDeformation of Metals will help practicing engineers and advancedstudents in mechanical, aerospace, civil, and metallurgicalengineering increase their professional skills in the moderntechnological environment.
