Download Transport Modeling of Hydrogen in Metals for Application to Hydrogen Assisted Cracking of Metals Book in PDF, ePub and Kindle
The focus of this research was on the development of a finite element code for solute transport and trapping in linear elastic mixtures for use in modeling the hydrogen transport process in metals undergoing hydrogen assisted cracking. Specific objectives included: (1) Completion of the development of a solute transport and trapping model with coupling between the concentration, deformation, and thermal field variables and trapping at reversible and irreversible trap sites. (2) Implementation of the above theory in a finite element code. (3) Calculation of the crack tip deformations and chemical state variables for some high strength steels under a variety of loading, environment, and material conditions. (MM).

Download The Kinetic and Mechanical Aspects of Hydrogen-induced Failure in Metals Book in PDF, ePub and Kindle
Premature hydrogen-induced failure observed to occur in many metal systems involves three stages of fracture: (1) crack initiation, (2) stable slow crack growth, and (3) unstable rapid crack growth. The presence of hydrogen at some critical location on the metal surface or within the metal lattice was shown to influence one or both of the first two stages of brittle fracture but has a negligible effect on the unstable rapid crack growth stage. The relative influence of the applied parameters of time, temperature, etc., on the propensity of a metal to exhibit hydrogen induced premature failure was investigated.

Download Gaseous Hydrogen Embrittlement of Materials in Energy Technologies Book in PDF, ePub and Kindle
Many modern energy systems are reliant on the production, transportation, storage, and use of gaseous hydrogen. The safety, durability, performance and economic operation of these systems is challenged by operating-cycle dependent degradation by hydrogen of otherwise high performance materials. This important two-volume work provides a comprehensive and authoritative overview of the latest research into managing hydrogen embrittlement in energy technologies. Volume 2 is divided into three parts, part one looks at the mechanisms of hydrogen interactions with metals including chapters on the adsorption and trap-sensitive diffusion of hydrogen and its impact on deformation and fracture processes. Part two investigates modern methods of modelling hydrogen damage so as to predict material-cracking properties. The book ends with suggested future directions in science and engineering to manage the hydrogen embrittlement of high-performance metals in energy systems. With its distinguished editors and international team of expert contributors, Volume 2 of Gaseous hydrogen embrittlement of materials in energy technologies is an invaluable reference tool for engineers, designers, materials scientists, and solid mechanicians working with safety-critical components fabricated from high performance materials required to operate in severe environments based on hydrogen. Impacted technologies include aerospace, petrochemical refining, gas transmission, power generation and transportation. Summarises the wealth of recent research on understanding and dealing with the safety, durability, performance and economic operation of using gaseous hydrogen at high pressure Chapters review mechanisms of hydrogen embrittlement including absorption, diffusion and trapping of hydrogen in metals Analyses ways of modelling hydrogen-induced damage and assessing service life

Download Hydrogen Transport in Hydride and Non-hydride Forming Metals and the Mechanistic Implications for Fracture Behavior Book in PDF, ePub and Kindle
Despite intense research, a complete mechanistic understanding of the hydrogen embrittlement phenomenon has yet to be achieved. Regardless of the specific mechanism of hydrogen embrittlement, a better understanding of hydrogen transport, hydride formation and their mechanistic effects on stress and strain is needed to elucidate the role of hydrogen in the mechanics of fracture. The thesis consists of five distinct projects, thereby allowing for the analysis of stress induced hydrogen transport in different systems under varying degrees of model complexity. The metal-hydrogen systems are modeled using a continuum mechanics approach and the solutions are obtained via iterative numerical methods. The first project examines the interaction of solute hydrogen atoms with the stress field of a sharp crack in an elastic material under equilibrium conditions. The effect of hydrogen induced volume dilatation and modulus softening on the crack tip stress fields is examined. In the next project, transient hydrogen transport and elastically accommodated hydride formation near a stationary sharp crack in an elastic material are analyzed. The third project considers the competition between hydrostatic stress and plastic strain in determining the interstitial and trapped hydrogen concentrations near a stress concentration in an elastoplastic material. Recent experimental data are considered in the fourth project, in which parameter studies are performed to gain insight into the factors responsible for the development of enhanced hydrogen concentrations in the nickel superalloy, X-750. In the final project, transient hydrogen diffusion and hydride formation near a stationary crack tip in an elastoplastic material are examined. A formulation for determining the effect of an external stress on the terminal solid solubility of hydrogen in an elastoplastic material is presented. A criterion for fracture via hydride formation and subsequent brittle cleavage is proposed and the fracture toughness of a cracked specimen in the presence of hydrogen is shown to be dependent on the tensile loading rate.
