DETERMINATION D'UN POINT CRITIQUE DE MISCIBILITE A L'ETAT SOLIDE ET D'UN POINT D'EVANOUISSEMENT DE LA LIGNE MONOVARIANTE DE LIQUIDUS CORRESPONDANTE written by KARINE.. JARDET and published by . This book was released on 1998 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: A LA SUITE D'UN PREMIER TRAVAIL EXPERIMENTAL SUR LE DIAGRAMME AL-ZN-GA, LA PRESENTE ETUDE PRECISE CERTAINS PHENOMENES INEDITS DU DIAGRAMME DE PHASES : UNE MISCIBILITE RETROGRADE DU GALLIUM DANS UNE SOLUTION SOLIDE AL-ZN CONDUISANT A UNE INVERSION DE CRISTALLISATION-FUSION (UN ALLIAGE PARTIELLEMENT LIQUIDE CRISTALLISE AU CHAUFFAGE PUIS FOND PARTIELLEMENT AU REFROIDISSEMENT). CES COMPORTEMENTS, SURPRENANTS A PRIORI, ONT ETE ETUDIES PAR DE MULTIPLES TECHNIQUES EXPERIMENTALES : ANALYSE CALORIMETRIQUE A FLUX, DIFFRACTION DES RAYONS X ET DES NEUTRONS A TEMPERATURE VARIABLE, THERMODILATOMETRIE ET MICROSCOPIE ELECTRONIQUE A BALAYAGE. CETTE ETUDE A ETE MENEE PAR LA METHODE DES COUPES ISOPLETHIQUES. LA COUPE ZA40-GA S'APPUIE SUR LA PAROI BINAIRE AL-ZN AU VOISINAGE DU MAXIMUM DE LA LACUNE DE MISCIBILITE DES PHASES SS# ET SS## BINAIRES. ELLE A ETE CHOISIE POUR DETERMINER LES COORDONNEES DU POINT CRITIQUE MAXIMUM TERNAIRE SS# SS##. LA COUPE ZA55-GA A ETE CHOISIE POUR TENTER DE DELIMITER LE DOMAINE D'EXISTENCE DE LA SOLUTION SOLIDE SS## TERNAIRE. TROIS ISOPLETHES (A 40, 50 ET 60% DE GA) ONT ETE PARTIELLEMENT ETUDIEES. ELLES ONT PERMIS DE PRECISER LES COORDONNEES DU POINT D'EVANOUISSEMENT DE LA LIGNE MONOVARIANTE DES LIQUIDES EN EQUILIBRE AVEC LES SOLUTIONS SOLIDES SS# ET SS##. HUIT ISOTHERMES, A 90, 150, 200, 250, 265, 280, 300 ET 360C, ONT ETE TRACEES. L'OBSERVATION M.E.B. ET LA MICROANALYSE DES PHASES DANS DES MELANGES TREMPES, APRES RECUIT, ONT CONFIRME LE TRACE DE CES COUPES. PAR DIFFRACTION DES NEUTRONS, NOUS AVONS CONFIRME ET COMPLETE LES RESULTATS DE LA DIFFRACTION DES RAYONS X A TEMPERATURE VARIABLE DANS LES DOMAINES PRESENTANT DES TRANSFORMATIONS DE PHASES LIQUIDE SOLIDE AU CHAUFFAGE ET SOLIDE LIQUIDE AU REFROIDISSEMENT. UNE SIMULATION A ETE EFFECTUEE A PARTIR DU MODELE DES CLUSTERS SUR LE FOND DIFFUS DES LIQUIDES EN EQUILIBRE AVEC DES SOLIDES C.F.C. ET H.C. A 100C ET DES LIQUIDES EN EQUILIBRE AVEC DES SOLIDES C.F.C. ET RHOMBOEDRIQUE A 140C. CES RESULTATS ONT PERMIS DE PRECISER LES TYPES D'ASSOCIATIONS EN PHASE LIQUIDE DANS CES ALLIAGES TERNAIRES.

This book was released on 1996 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'OBJET DE CE TRAVAIL EST D'APPORTER UNE MEILLEURE CONNAISSANCE DES CARACTERISTIQUES MICROSTRUCTURALES ET CHIMIQUES DES INTERMETALLIQUES A BASE TIAL AINSI QUE DES MECANISMES QUI GOUVERNENT CERTAINES TRANSFORMATIONS DE PHASES INTERVENANT DANS CES ALLIAGES. LA PREMIERE PARTIE DE L'ETUDE CONCERNE LE ROLE DE L'OXYGENE, FACTEUR REPUTE COMME DETERMINANT, SUR LA DUCTILITE A TEMPERATURE AMBIANTE DES ALLIAGES TIAL. DEUX RESULTATS IMPORTANTS ONT ETE ETABLIS : I) LA LOCALISATION PREFERENTIELLE DE L'OXYGENE DANS LA PHASE ALPHA DEUX ET II) LA SOLUBILITE MAXIMALE DE L'OXYGENE DE L'ORDRE DE TROIS CENTS PPM ATOMIQUES DANS LA PHASE GAMMA A L'EQUILIBRE. L'INFLUENCE DE DIFFERENTS PARAMETRES (STOECHIOMETRIE DES PHASES, TENEUR GLOBALE EN OXYGENE, ADDITION D'UN TROISIEME ELEMENT) SUR CETTE SOLUBILITE A ETE ETUDIEE. L'INTERPRETATION DE CES RESULTATS EN TERME D'ENVIRONNEMENT CHIMIQUE DES SITES INTERSTITIELS FAVORABLES A LA LOCALISATION DE L'OXYGENE A ETE PROPOSEE. DEUX TRANSFORMATIONS DE PHASES ONT ETE ETUDIEES DANS LA DEUXIEME PARTIE : LA FORMATION DE LA PHASE ALPHA DEUX DANS LA STRUCTURE LAMELLAIRE ET LA TRANSFORMATION MASSIVE DE ALPHA EN GAMMA. A PARTIR DES RESULTATS EXPERIMENTAUX, LE ROLE DE L'OXYGENE EST DISCUTE VIS-A-VIS DES MECANISMES REGISSANT CES TRANSFORMATIONS. EN PARTICULIER, L'OXYGENE CONDUIT A LA PRESENCE DE FAUTES DANS LA PHASE GAMMA MASSIVE ET EMPECHE LA TRANSFORMATION MASSIVE D'ETRE COMPLETE. DANS LA DERNIERE PARTIE, LE ROLE DES ELEMENTS D'ADDITION ET LEUR REPARTITION ENTRE LES PHASES SONT ETUDIES DANS UN ALLIAGE QUATERNAIRE BIPHASE (ALPHA DEUX+GAMMA) CONTENANT DU CHROME ET DU NIOBIUM. UNE INTERPRETATION DU COMPORTEMENT A LA FOIS GAMMA-PHILE ET ALPHA-DEUX GENE DU NIOBIUM A ETE DONNEE A PARTIR DE LA FORME DES LOBES DE SOLUBILITE DANS LES COUPES ISOTHERMES DE DIAGRAMMES TERNAIRES.

NOUS AVONS AINSI ETABLI, TROIS SECTIONS ISOPLETES A 42,5, 50 ET 56% AT. DE TITANE ET UNE PROJECTION DU LIQUIDUS TERNAIRE. QUATRE SECTIONS ISOTHERMES A 1350, 900, 800 ET 700C SONT EGALEMENT PROPOSEES. UN ATLAS DES MICROSTRUCTURES EST ETABLI. CELLES-CI SONT TRES SENSIBLES AUX VARIATIONS DE COMPOSITION, DE TEMPERATURE ET DE DUREE DE MAINTIEN ISOTHERME. LA PHASE BETA/B2 DE HAUTE TEMPERATURE SE DECOMPOSE SELON CINQ CHEMINS ABOUTISSANT A DES DOMAINES DE PHASES DIFFERENTS : B2+O, SIGMA+O, SIGMA+O+OMEGA, ALPHA2+GAMMA+OMEGA ET ALPHA2+O+OMEGA, EN FONCTION DE LA TENEUR DE NIOBIUM CONTENUE DANS CES ALLIAGES. HORS D'EQUILIBRE, PLUSIEURS TRANSFORMATIONS ORIGINALES SONT MISES EN EVIDENCE. LA PHASE ORTHORHOMBIQUE SE FORME PAR UNE TRANSFORMATION MASSIVE A PARTIR DE LA PHASE B2 POUR DES ALLIAGES CENTRES AUTOUR DU COMPOSE A1NBTI2.

Book Synopsis From Microphysics to Macrophysics by : Roger Balian
Download or read book From Microphysics to Macrophysics written by Roger Balian and published by Springer Science & Business Media. This book was released on 2007-06-26 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: This popular, often cited text returns in a softcover edition to provide a thorough introduction to statistical physics and thermodynamics, and to exhibit the universal chain of ideas leading from the laws of microphysics to the macroscopic behaviour of matter. A wide range of applications illustrates the concepts, and many exercises reinforce understanding. Volume II applies statistical methods to systems governed by quantum effects, in particular to solid state physics, explaining properties due to the crystal structure or to the lattice excitations or to the electrons. The last chapters are devoted to non-equilibrium processes and to kinetic equations, with many applications included.

Book Synopsis Four Laws That Drive the Universe by : Peter Atkins
Download or read book Four Laws That Drive the Universe written by Peter Atkins and published by OUP Oxford. This book was released on 2007-09-06 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal, and from the unfurling of a leaf to the course of life itself - everything is directed and constrained by four simple laws. They establish fundamental concepts such as temperature and heat, and reveal the arrow of time and even the nature of energy itself. Peter Atkins' powerful and compelling introduction explains what the laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader from the Zeroth Law to the Third Law, he introduces the fascinating concept of entropy, and how it not only explains why your desk tends to get messier, but also how its unstoppable rise constitutes the engine of the universe.
