This book was released on 2007 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les alliages basés sur les composés intermétalliques de type Fe-Al possèdent encore aujourd'hui une forte attractivité pour des applications industrielles, du fait de nombreuses propriétés intéressantes : tenue mécanique à relativement haute température, résistance à l'oxydation, faible coût d'élaboration. Cette thèse porte sur deux caractéristiques de ces familles d'alliages: i) les défauts microstructuraux, en particulier ceux liés aux phénomènes de mise en ordre et ii) l'oxydation à haute température. Nous avons travaillé sur quatre alliages différents : un alliage binaire Fe-40Al, deux alliages contenant des éléments d'addition (Fe-40Al-0,01B et Fe-40Al-2,7Ni-0,02B) et un alliage semi industriel (grade 3 contenant plusieurs éléments d'addition – Ni, Mn, Cr, Mo, B - et des particules de Y2O3). De plus, des couples de diffusion ont été réalisés entre chacun de ces alliages et du fer. Ces couples nous ont permis d'étudier les phénomènes de diffusion et de disposer d'échantillons avec une teneur variable en aluminium. Au cours de la caractérisation microstructurale des alliages nous avons analysé les défauts plans complexes liés à la présence de bore. L'étude des couples de diffusion a été réalisée par analyse chimique (EDS) et par l'observation en microscopie électronique en transmission des différents domaines créés par la mise en ordre au cours des traitements thermiques (domaines d'antiphase APD). Ces résultats permettent de révéler l'influence de la composition des alliages sur la diffusion et les températures de transformation. Nous montrons en particulier que l'addition de nickel ralentit la diffusion et semble étendre le domaine d'existence de la phase B2. L'étude de la cinétique d'oxydation a été menée par analyse thermogravimétrique à 800 et 1000°C sur les différents alliages fer-aluminium ainsi que sur des sections des couples de diffusion. Les résultats des prises de masse complétées par l'analyse en diffraction de rayons X et par des observations en MEB permettent de préciser la nature des oxydes formés en fonction de la composition des alliages. Nous avons pu ainsi préciser la teneur minimale d'aluminium nécessaire pour bloquer l'oxydation du fer (19 %at.) et le rôle du nickel sur la cinétique d'oxydation

Book Synopsis Dislocations, Mesoscale Simulations and Plastic Flow by : Ladislas Kubin
Download or read book Dislocations, Mesoscale Simulations and Plastic Flow written by Ladislas Kubin and published by OUP Oxford. This book was released on 2013-04-18 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past twenty years, new experimental approaches, improved models and progress in simulation techniques brought new insights into long-standing issues concerning dislocation-based plasticity in crystalline materials. During this period, three-dimensional dislocation dynamics simulations appeared and reached maturity. Their objectives are to unravel the relation between individual and collective dislocation processes at the mesoscale, to establish connections with atom-scale studies of dislocation core properties and to bridge, in combination with modelling, the gap between defect properties and phenomenological continuum models for plastic flow. Dislocation dynamics simulations are becoming accessible to a wide range of users. This book presents to students and researchers in materials science and mechanical engineering a comprehensive coverage of the physical body of knowledge on which they are based. It includes classical studies, which are too often ignored, recent experimental and theoretical advances, as well as a discussion of selected applications on various topics.

Book Synopsis Minerals in Africa by : Francis Gudyanga
Download or read book Minerals in Africa written by Francis Gudyanga and published by CRC Press. This book was released on 2020-08-10 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa’s dire need to industrialize is universally acknowledged and it is evident that the continent’s vast mineral resources can catalyze that industrialization. This requires the promotion of local beneficiation and value addition of minerals to yield materials on which modern Africa’s industry and society can rely. This book is, therefore, about transforming Africa’s comparative advantages in minerals into the continent’s competitive edge regarding materials. Mineral beneficiation and value addition form the basis and provide opportunities for mineral-driven Africa’s industrialization. The scope of the book is three-fold with inter-connected relationships: Information, Technical, and Policy oriented. It will be a useful reference material for mining undergraduate students on beneficiation and value addition of each of the minerals found in Africa. The book, while presenting a broad overview of beneficiation and value addition of Africa’s minerals, provides crucial starting material for postgraduate research students and R&D institutions who wish to delve into more advanced methods of extraction and utilization of mineral-derived materials that are in Africa for the purpose of industrialization of the continent.
Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Book Synopsis Fundamentals of Aircraft and Rocket Propulsion by : Ahmed F. El-Sayed
Download or read book Fundamentals of Aircraft and Rocket Propulsion written by Ahmed F. El-Sayed and published by Springer. This book was released on 2016-05-25 with total page 1025 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive basics-to-advanced course in an aero-thermal science vital to the design of engines for either type of craft. The text classifies engines powering aircraft and single/multi-stage rockets, and derives performance parameters for both from basic aerodynamics and thermodynamics laws. Each type of engine is analyzed for optimum performance goals, and mission-appropriate engines selection is explained. Fundamentals of Aircraft and Rocket Propulsion provides information about and analyses of: thermodynamic cycles of shaft engines (piston, turboprop, turboshaft and propfan); jet engines (pulsejet, pulse detonation engine, ramjet, scramjet, turbojet and turbofan); chemical and non-chemical rocket engines; conceptual design of modular rocket engines (combustor, nozzle and turbopumps); and conceptual design of different modules of aero-engines in their design and off-design state. Aimed at graduate and final-year undergraduate students, this textbook provides a thorough grounding in the history and classification of both aircraft and rocket engines, important design features of all the engines detailed, and particular consideration of special aircraft such as unmanned aerial and short/vertical takeoff and landing aircraft. End-of-chapter exercises make this a valuable student resource, and the provision of a downloadable solutions manual will be of further benefit for course instructors.
