Book excerpt: This thesis is a theoretical exploration of properties of multilayered and multicomponent nitride alloys, in particular their mixing thermodynamics and elastic behaviors. Systematic investigation of properties of a large class of materials, such as the multicomponent nitride solid solutions, is in line with the modern approach of high-throughput search of novel materials. In this thesis we benchmark and utilize simple but efficient methodological frameworks in predicting mixing thermodynamics, Young’s moduli distribution of multilayer alloys and the linear thermal expansion of quaternary nitride solid solutions. We demonstrate by accurate ab-initio calculations that Ti1−xAlxN solid solution is stabilized by interfacial effects if it is coherently sandwiched between TiN layers along (001). For TiN/AlN and ZrN/AlN multilayers we show higher thermodynamic stability with semicoherent interfaces than with isostructural coherent ones. Accurate 0 Kelvin elastic constants of cubic TixXyAl1−x−yN (X=Zr, Hf, Nb, V, Ta) solid solutions and their multilayers are derived and an analytic comparison of strengths and ductility are presented to reveal the potential of these materials in hard coating applications. The Young’s moduli variation of the bulk materials has provided a reliable descriptor to screen the Young’s moduli of coherent multilayers. The Debye model is used to reveal the high-temperature thermodynamics and spinodal decomposition of TixNbyAl1−x−yN. We show that though the effect of vibration is large on the mixing Gibbs free energy the local spinoal decomposition tendencies are not altered. A quasi-harmonic Debye model is benchmarked against results of molecular dynamics simulations in predicting the thermal expansion coefficients of TixXyAl1−x−yN (X=Zr, Hf, Nb, V, Ta). Denna avhandling är en teoretisk undersökning av egenskaperna hos multilager och multikomponentlegeringar av nitrider, särskilt deras blandningstermodynamik och elastiska egenskaper. Systematiska undersökningar av egenskaperna hos en stor materialfamilj, såsom fasta lösningar av multikomponentnitrider, ligger i linje med den moderna angreppsvinkeln av massundersökningar i sökandet efter nya material. I denna avhandling utvärderar och använder vi enkla men effektiva metodologiska ramverk för att förutsäga blandningstermodynamik, fördelning av Young’s moduli multilager och den linjära termiska expansionen i kvaternära fasta lösningar av nitrider. Vi visar med precisa ab-initio-beräkningar att en fast lösning av Ti1−xAlxN stabiliseras av gränssnittseffekter om den placeras koherent mellan TiN-skikt längs med (001). För multilager av TiN/AlN och ZrN/AlN påvisar vi högre termodynamisk stabilitet med semikoherenta gränsskikt än med isostrukturella koherenta. Precisa elastiska konstanter vid 0 K för kubiska fasta lösningar av TixXyAl1−x−yN (X=Zr, Hf, Nb, V, Ta) och deras multilager beräknas och en analytisk jämförelse av deras hållfasthet och duktilitet presenteras för att visa dessa materials potential som hårda beläggningar. Variationen av Young’s moduli materialen i bulk har gett en pålitlig deskriptor för att undersöka Young’s moduli koherenta multilager. Debye-modellen används för att undersöka hög-temperatur-termodynamiken och spinodalt sönderfall hos TixNbyAl1−x−yN. Vi visar att trots att vibrationers effekt på Gibbs fria energi för blandning är stor påverkas inte de lokala tendenserna för spinodalt sönderfall. En kvasiharmonisk Debye-modell jämförs med resultat från molekyldynamiksimuleringar för att förutsäga utvidgningskoefficienter för TixXyAl1−x−yN (X=Zr, Hf, Nb, V, Ta). Diese Arbeit ist eine theoretische Untersuchung der Eigenschaften von mehrschichtigen und mehrkomponentigen Nitridlegierungen, insbesondere deren Mischungs- Thermodynamik und elastischen Verhalten. Eine systematische Untersuchung von Eigenschaften einer großen Klasse von Materialien, wie zum Beispiel fester Lösungen von Mehrkomponenten-Nitriden, ist im Einklang mit dem zeitgenössischen Hochdurchsatzverfahren für die Suche nach neuen Materialien. In dieser Arbeit benchmarken und nutzen wir einfache, aber effiziente methodische Frameworks zur Vorhersage der Mischungs-Thermodynamik, der Verteilung des Elastizitätsmoduls von Mehrschichtlegierungen und der linearen thermischen Ausdehnung von festen, quaternären Nitrid-Lösungen. Wir zeigen durch genaue Ab-initio-Berechnungen, dass Ti1−xAlxN Mischkristalle durch Grenzflächenwirkungen stabilisiert werden, wenn sie kohärent zwischen TiN Schichten entlang (001) sandwichartig angeordnet sind. Die genauen elastischen Konstanten von kubischen TixXyAl1−x−yN (X = Zr, Hf, Nb, V, Ta) Mischkristallen und deren Mehrfachschichten bei 0 Kelvin werden abgeleitet und ein analytischer Vergleich der Festigkeit und Duktilität zeigt das Potential dieser Materialien in Hartbeschichtungsanwendungen. Das Debye-Modell wird verwendet, um die Hochtemperatur-Thermodynamik und die spinodale Entmischung von TixNbyAl1−x−yN aufzudecken. Wir zeigen, dass sich die lokale Tendenzen zur spinodalen Entmischung nicht ändern, obwohl die Wirkung von Vibrationen auf die Gibbs-Energie großist. Ein quasi-harmonisches Debye-Modell wird gegen die Ergebnisse von Moleküldynamik-Simulationen gebenchmarkt, um die thermische Ausdehnungskoeffizienten von TixXyAl1−x−yN (X=Zr, Hf, Nb, V, Ta) vorherzusagen.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook offers a strong introduction to the fundamental concepts of materials science. It conveys the quintessence of this interdisciplinary field, distinguishing it from merely solid-state physics and solid-state chemistry, using metals as model systems to elucidate the relation between microstructure and materials properties. Mittemeijer's Fundamentals of Materials Science provides a consistent treatment of the subject matter with a special focus on the microstructure-property relationship. Richly illustrated and thoroughly referenced, it is the ideal adoption for an entire undergraduate, and even graduate, course of study in materials science and engineering. It delivers a solid background against which more specialized texts can be studied, covering the necessary breadth of key topics such as crystallography, structure defects, phase equilibria and transformations, diffusion and kinetics, and mechanical properties. The success of the first edition has led to this updated and extended second edition, featuring detailed discussion of electron microscopy, supermicroscopy and diffraction methods, an extended treatment of diffusion in solids, and a separate chapter on phase transformation kinetics. “In a lucid and masterly manner, the ways in which the microstructure can affect a host of basic phenomena in metals are described.... By consistently staying with the postulated topic of the microstructure - property relationship, this book occupies a singular position within the broad spectrum of comparable materials science literature .... it will also be of permanent value as a reference book for background refreshing, not least because of its unique annotated intermezzi; an ambitious, remarkable work.” G. Petzow in International Journal of Materials Research. “The biggest strength of the book is the discussion of the structure-property relationships, which the author has accomplished admirably.... In a nutshell, the book should not be looked at as a quick ‘cook book’ type text, but as a serious, critical treatise for some significant time to come.” G.S. Upadhyaya in Science of Sintering. “The role of lattice defects in deformation processes is clearly illustrated using excellent diagrams . Included are many footnotes, ‘Intermezzos’, ‘Epilogues’ and asides within the text from the author’s experience. This ..... soon becomes valued for the interesting insights into the subject and shows the human side of its history. Overall this book provides a refreshing treatment of this important subject and should prove a useful addition to the existing text books available to undergraduate and graduate students and researchers in the field of materials science.” M. Davies in Materials World.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this text is to provide some insight into chemical defects in crystalline solids. Chemical defects, which are mistakes or changes in the atomic make-up of the crystals, have far-reaching effects on the composition, optical properties and electronic properties of materials. The area is therefore of relevance to chemists, physicists, materials scientists and engineers. The book has been designed to be read by students with no prior knowledge of the subject, but with a background in basic chemistry and physics. It begins with relatively simple ideas but progresses into a discussion of complex materials, at the forefront of research in the field. The links between principles and applications have been strengthened in the text by the inclusion of a series of case studies. In addition, the crystal structures that are of most importance have been described throughout the book in a series of boxes, to provide a crystallographic reference within the text.
