CES NOUVELLES DONNEES THERMODYNAMIQUES, ONT PERMIS DE PROPOSER UNE NOUVELLE OPTIMISATION DU SYSTEME U-FE. L'ETUDE DU SYSTEME TERNAIRE U-FE-O A ETE ENTREPRISE EN ETABLISSANT LA SECTION ISOTHERME A 1300 K. LES PHASES OBTENUES ONT ETE CARACTERISEES PAR DRX, MICROSCOPIE ELECTRONIQUE EN TRANSMISSION, MEB ET MICROSONDE. EN RAISON DES LIMITES DE CES TECHNIQUES, IL A ETE NECESSAIRE D'INTERPRETER LES RESULTATS SUR LA BASE DES DONNEES THERMODYNAMIQUES ET EN PARTICULIER DES POTENTIELS D'OXYGENE. POUR COMPLETER, CES DONNEES DE DIAGRAMME DE PHASE, LE POTENTIEL D'OXYGENE D'EQUILIBRE DE CERTAINS DOMAINES TRIPHASES A ETE DETERMINE PAR THERMOGRAVIMETRIE. DE PLUS, UNE ETUDE THERMODYNAMIQUE ET STRUCTURALE A ETE FAITE SUR LE COMPOSE UFEO 4. SA STRUCTURE, DEJA ETABLIE, A ETE CONFIRMEE ; SON ENTHALPIE DE FORMATION ET SA CAPACITE THERMIQUE ONT ETE MESUREES PAR CALORIMETRIE. DES ANALYSES DE DRX A HAUTE TEMPERATURE ONT PERMIS DE STATUER SUR LA STABILITE THERMIQUE DE CE MATERIAU ET DE METTRE EN EVIDENCE L'EXISTENCE D'UN NOUVEL OXYDE TERNAIRE UFEO 4 . 5, DONT LA STRUCTURE A ETE ETABLIE DANS CETTE ETUDE. L'ENSEMBLE DE CES DONNEES ORIGINALES PERMETTENT DE CORRELER LES TROIS SYSTEMES BINAIRES AVEC LE TERNAIRE ET AINSI DE PROPOSER UNE DESCRIPTION REALISTE DU DIAGRAMME DE PHASE U-FE-O EN PHASE SOLIDE.

This book was released on 2020-08-06 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication results from a technical meeting on phenomenology and technologies relevant to in-vessel melt retention (IVMR) and ex-vessel corium cooling (EVCC). The purpose of the publication is to capture the state of knowledge, at the time of that meeting, related to phenomenology and technologies as well as the challenges and pending issues relevant to IVMR and EVCC for water cooled reactors by summarizing the information provided by the meeting participants in a form useful to practitioners in Member States.

Download or read book CALPHAD Calculation of Phase Diagrams A Comprehensive Guide written by N. Saunders and published by Elsevier. This book was released on 1998-06-09 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph acts as a benchmark to current achievements in the field of Computer Coupling of Phase Diagrams and Thermochemistry, often called CALPHAD which is an acronym for Computer CALculation of PHAse Diagrams. It also acts as a guide to both the basic background of the subject area and the cutting edge of the topic, combining comprehensive discussions of the underlying physical principles of the CALPHAD method with detailed descriptions of their application to real complex multi-component materials.Approaches which combine both thermodynamic and kinetic models to interpret non-equilibrium phase transformations are also reviewed.

This book was released on 2013-06-29 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Institute for Amorphous Studies was founded in 1982 as the international center for the investigation of amorphous mate rials. It has since played an important role in promoting the und er standing of disordered matter in general. An Institute lecture series on "Fundamentals of Amorphous Materials and Devices" was held during 1982-83 with distinguished speakers from universities and industry. These events were free and open to the public ,and were attended by many representatives of the scientific community. The lectures themselves were highly successful inasmuch as they provided not only formal instruction but also an opportunity for vigorous and stimulating debate. That last element could not be captured within the pages of a book I but the lectures concentrated on the latest advances in the field I which is why their essential contents are he re reproduced in collective form. Together they constitute an interdisciplinary status report of the field. The speakers brought many different viewpoints and a variety of back ground experiences io bear on the problems involved I but though language and conventions vary I the essential unity of the concerns is very clear I as indeed are the ultimate benefits of the many-sided approach.

Available in PDF, EPUB and Kindle. Book excerpt: Phase diagrams are "maps" materials scientists often use to design new materials. They define what compounds and solutions are formed and their respective compositions and amounts when several elements are mixed together under a certain temperature and pressure. This monograph is the most comprehensive reference book on experimental methods for phase diagram determination. It covers a wide range of methods that have been used to determine phase diagrams of metals, ceramics, slags, and hydrides.* Extensive discussion on methodologies of experimental measurements and data assessments * Written by experts around the world, covering both traditional and combinatorial methodologies* A must-read for experimental measurements of phase diagrams

Download or read book Neutron Capture Gamma Ray Spectroscopy written by R. E. Chrien and published by Springer. This book was released on 2011-12-29 with total page 880 pages. Available in PDF, EPUB and Kindle. Book excerpt: The post World War II era witnessed a tremendous growth in the research carried out in neutron-induced reactions and especially in neutron capture y-ray studies. This growth was stimulated by the availability of neutron sources, such as reactors and accelerators, and by the development of high resolution y-ray and conversion electron detectors. Today the combination of high flux reactors and precise instrumentation has produced spectral data of exceptional quality, as the pages of these proceedings illustrate. The world-wide community of the practioners of the art of cap ture y-ray spectroscopy has met three times in the last decade: the first international symposium on this subject was held at Studsvik, Sweden in 1969, and the second at Petten, The Netherlands in 1974. A smaller meeting, of mostly u. S. and some European parti cipation, was held at Argonne National Laboratory in 1966. A perusal of the proceedings of these meetings shows the striking ad vances in this now mature field of physics over the last dozen years. Each meeting has seen a small but perceptible increase in the number of papers presented and the number of laboratories repre sented. More importantly, each meeting has documented the increasing impact of (n,y) reasearch, not only on other areas of basic physics, but also on commercial and medical applications of this technology. A total of 29 invited papers and 97 contributed papers were presented at this symposium.
