Book excerpt: CE TRAVAIL A CONSISTE A ETUDIER LES TRANSITIONS DE PHASE STRUCTURALES DANS LA SOLUTION SOLIDE P(CH#3)#4#2(CUCL#4)#1##X(CUBR#4)#X DONT LES SEQUENCES DE PHASE SONT PILOTEES PAR DEUX PARAMETRES D'ORDRE DIFFERENTS. LE GROUPE D'ESPACE DE LA PHASE HAUTE TEMPERATURE EST PNMA. LE PREMIER PARAMETRE D'ORDRE CORRESPOND AU COMPOSE PUR CHLORE P(CH#3)#4#2(CUCL#4) POUR LEQUEL L'INSTABILITE SE DEVELOPPE DANS LA DIRECTION CRISTALLOGRAPHIQUE A (DONNANT UNE PHASE INCOMMENSURABLE SUIVIE A BASSE TEMPERATURE PAR UNE PHASE COMMENSURABLE AVEC Q=A*/3), TANDIS QUE L'AUTRE PARAMETRE D'ORDRE CORRESPOND AU COMPOSE BROME PUR P(CH#3)#4#2CUBR#4 OU L'INSTABILITE SE DEVELOPPE DANS LA DIRECTION C. DANS LA SOLUTION SOLIDE LE COUPLAGE ENTRE LES DEUX PARAMETRES D'ORDRE PEUT CONDUIRE A UNE SEQUENCE DE TRANSITIONS DU TYPE BR A HAUTE TEMPERATURE ET DU TYPE CL A BASSE TEMPERATURE DANS UN CERTAIN DOMAINE DE COMPOSITION X. NOUS AVONS PLUS PARTICULIEREMENT TRAVAILLE SUR LE COMPOSE X=0.125. SA SEQUENCE DE TRANSITIONS MONTRE PLUSIEURS PHENOMENES INTERESSANTS QUI RESULTENT DU COUPLAGE ENTRE LES DEUX PARAMETRES D'ORDRE, NOTAMMENT UNE FACE DOUBLEMENT MODULEE (DANS LES DEUX DIRECTIONS A ET C SIMULTANEMENT) ET UN COMPORTEMENT RE-ENTRANT DU PARAMETRE D'ORDRE DU TYPE BR. UN MODELE D'INTERPRETATION DES SEQUENCES DE PHASE DES COMPOSES PURS ET DE LA SOLUTION SOLIDE DANS LE CADRE DE LA THEORIE PHENOMENOLOGIQUE DE LANDAU EST PROPOSE DANS LE CHAPITRE V. CE MODELE PERMET DE PREVOIR LES PHASES INCOMMENSURABLES, LES GROUPES D'ESPACE DES PHASES COMMENSURABLES ET IL EXPLIQUE EN PARTICULIER LE PHENOMENE DE SYMETRIE RE-ENTRANTE OBSERVE DANS LA SOLUTION SOLIDE

Download or read book Transformations entre phases written by Michel Soustelle and published by ISTE Group. This book was released on 2016-02-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: La série Thermodynamique chimique approfondie présente l’ensemble des thèmes de la thermodynamique utiles à la chimie, aux matériaux, à l’électrochimie, aux phénomènes de surface et au génie des procédés. Cet ouvrage est consacré à l’étude des transformations et des équilibres entre phases. Les transformations des phases pures du premier et du second ordre sont présentées en détail, tout comme les approches macroscopiques et microscopiques des équilibres de phases. Dans la présentation des systèmes binaires, les thermodynamiques de l’azéotropie et de la démixtion sont approfondies et appliquées aux solutions strictement régulières. Les points eutectiques et péritectiques sont examinés, ainsi que les réactions qui les accompagnent. L’étude des systèmes ternaires introduit quant à elle les notions d’azéotropes et d’eutectiques ternaires. Pour chaque type de systèmes solide-liquide les interventions de composés définis à fusion congruente ou non sont prises en compte. Les propriétés particulières des différents points remarquables d’un diagramme sont également démontrées.

Les trois derniers chapitres sont consacrés au rôle des microstructures et des nanostructures, aux transitions dans les films minces et aux phénomènes de transitions de phases dans les grands systèmes naturels et techniques. A la fin de chaque chapitre sont proposés des exercices, dont les solutions se trouvent en fin d'ouvrage, ainsi qu'une bibliographie de base.
Book Synopsis Phase Transitions and Relaxation in Systems with Competing Energy Scales by : T. Riste
Download or read book Phase Transitions and Relaxation in Systems with Competing Energy Scales written by T. Riste and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems with competing energy scales are widespread and exhibit rich and subtle behaviour, although their systematic study is a relatively recent activity. This text presents lectures given at a NATO Advanced Study Institute reviewing the current knowledge and understanding of this fascinating subject, particularly with regard to phase transitions and dynamics, at an advanced tutorial level. Both general and specific aspects are considered, with competitions having several origins; differences in intrinsic interactions, interplay between intrinsic and extrinsic effects, such as geometry and disorder; irreversibility and non-equilibration. Among the specific physical application areas are supercooled liquids and glasses, high-temperature superconductors, flux or vortex pinning and motion, charge density waves, domain growth and coarsening, and electron solidification.

Book Synopsis Reconstructive Phase Transitions by : Pierre Toldano
Download or read book Reconstructive Phase Transitions written by Pierre Toldano and published by World Scientific. This book was released on 1996 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the phenomenological theory of first-order structural phase transitions, with a special emphasis on reconstructive transformations in which a group-subgroup relationship between the symmetries of the phases is absent. It starts with a unified presentation of the current approach to first-order phase transitions, using the more recent results of the Landau theory of phase transitions and of the theory of singularities. A general theory of reconstructive phase transitions is then formulated, in which the structures surrounding a transition are expressed in terms of density-waves, providing a natural definition of the transition order-parameters, and a description of the corresponding phase diagrams and relevant physical properties. The applicability of the theory is illustrated by a large number of concrete examples pertaining to the various classes of reconstructive transitions: allotropic transformations of the elements, displacive and order-disorder transformations in metals, alloys and related structures, crystal-quasicrystal transformations.

Book Synopsis Phase Transitions in Solids Under High Pressure by : Vladimir Davydovich Blank
Download or read book Phase Transitions in Solids Under High Pressure written by Vladimir Davydovich Blank and published by CRC Press. This book was released on 2013-10-25 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of high-pressure techniques has become popular for studying the nature of substances and phenomena occurring in them, especially as a means of obtaining new materials (synthesis under high pressure) and processing known materials (hydroextrusion). A product of many years of research by the authors and their colleagues, Phase Transitions in Solids under High Pressure discusses the relationships of phase transformations in solids under high pressure, the mechanism of these transformations, crystal geometry, the effect of deformation, the conditions of formation, and preservation of the high-pressure phases under normal pressure. The book begins with an introduction that describes the relationship of the thermodynamics of phase transformations and the kinetics of the transformations. This is followed by a chapter explaining the equipment and mostly original procedures for investigating phase transformation in solids under high hydrostatic and quasi-hydrostatic pressures. The book covers phase transformations under high pressure in a wide temperature range in the elements carbon, silicon, germanium, titanium, zirconium, iron, gallium, and cerium as well as in titanium- and iron-based alloys and AIBVII, AIIBVI, and AIIIBV compounds. In addition, the book examines the kinetics of phase transformations in iron-based alloys in isobaric–isothermal conditions. The authors present results for phase transformations in deformation under high pressure, describe several non-trivial effects associated with phase transformations under high pressure, and analyze the kinetics and hysteresis of high-temperature and low-temperature phase transformations. They conclude by describing the role of investigations under high pressure for determining general relationships governing phase transformations in solids.
