Available in PDF, EPUB and Kindle. Book excerpt: This classic monograph on unsteady transonic flow — the flow of air encountered at speeds at or near the speed of sound — is of continuing interest to students and professionals in aerodynamics, fluid dynamics, and other areas of applied mathematics. After a brief Introduction, Swedish physicist Mårten T. Landahl presents a chapter in which the two-dimensional solution is derived, succeeded by a discussion of its relation to the subsonic and supersonic solutions. Three chapters on low aspect ratio configurations follow, covering triangular wings and similar planforms with curved leading edges, rectangular wings, and cropped delta wings, and low aspect ratio wing-body combinations. The treatment concludes with a consideration of the experimental determination of air forces on oscillating wings at transonic speeds.

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

Book excerpt: Orientation Imaging Microscopy (OIM) methods were applied to the analysis of the microstructure and microtexture as well as the deformation and failure modes of superplastic AA5083 aluminum alloys. Annealing of a cold-rolled AA5083 material at 450 deg C resulted in the formation of equiaxed grains approximately 7mum-8mum in size. Random grain-to-grain misorientations were consistent with particle-stimulated nucleation of recrystallization during processing for superplasticity. Such as microstructure is necessary for superplasticity but mechanical property data indicated only moderate ductility and failure by cavity formation and linkage. This investigation then employed OIM methods to identify the misorientations of boundaries prone to cavitation and determine the role of such boundaries in failure of these materials during elevated temperature deformation.

This book was released on 2018 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for low weight and high performance structural materials has revolutionized the technology and has led to the emergence of new processes and methodologies. Friction stir processing (FSP), based on the principle of friction stir welding, is an emerging solid state metal working process. This technique causes intense plastic deformation and high strain rates in the processed material, resulting in precise control of the microstructure through material mixing and densification. FSP process has been successfully used for achieving significant grain refinement and enhancement of surface properties. The present work focuses on the study of behavior of Aluminium cast alloy (Al-6063) processed by the friction stir processing technique. Samples of FSP-ed aluminium were examined and their microstructures, microhardness, Rockwell hardnesss and impact strength were studied and compared with base metal Al-6063. Hardness tester was employed to evaluate the interfacial bonding between the particles and matrix by indenting the hardness with the constant load and constant time. Impact test was employed to know the Impact Strength of samples against the Impact of Hammer.

This book was released on 2003 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: La microstructure des aciers et des fontes est une monographie sur la genèse et l'interprétation de la microstructure des aciers et des alliages à base fer. Ses 400 pages sont illustrées par de nombreuses micrographies d'alliages commerciaux ou d'alliages modèles à toutes les échelles disponibles avec les moyens d'investigation modernes de microscopie électronique, sans oublier la macro/microscopie optique. La première partie du livre est une introduction historique sur l'évolution des structures métallurgiques forgées manuellement depuis la connaissance du fer, en particulier les fameuses structures dites damassées. Le livre expose en deuxième partie les notions fondamentales de façon à fournir toutes les bases de raisonnement nécessaires sur les équilibres de phases et la cinétique des transformations. Concernant les équilibres de phases, de nombreux diagrammes sont inclus dans leur version la plus récente. La lecture des systèmes ternaires est analysée à propos de six systèmes représentatifs des réactions rencontrées dans les aciers, Fe-Cr-C, Fe-Ni-Cr, Fe-Mn-S, Fe-Co-Cu, Fe-Mo-Cr et Fe-C-V. Les structures de solidification sont étudiées à travers tous les cas classiques mais aussi dans d'autres moins banals comme les marquages des réactions péritectique ou métatectique ou des cascades de transformations. Les transformations en phase solide sont illustrées et commentées à l'aide des interprétations récentes, en particulier dans le cas des structures bainitiques. De nombreuses références permettent d'approfondir les aspects non développés. La troisième partie est un guide pour comprendre et discuter sur des bases scientifiques le rôle des éléments d'alliage et celui des divers traitements spécifiques aboutissant à l'optimisation des aciers et des fontes, définir les caractéristiques micrographiques en relation avec les propriétés d'emploi. Les aciers sont classés en familles depuis les aciers très peu alliés jusqu'à des aciers à fortes teneurs en éléments d'alliage résultant d'un ajustement de composition très pointue. Les fontes sont présentées naturellement en fonction de leur microstructure, classées en fontes blanches, grises lamellaires et nodulaires.
