Download or read book Nucleation of Voids in Metals During Diffusion and Creep written by R. Resnick and published by . This book was released on 1956 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental evidence is presented which proves that voids formed during diffusion in brass are heterogeneously nucleated. The nuclei appear to be oxide particles, probably ZnO. When these are removed by re-melting, voids practically do not form upon subsequent dezincification. Brass which had been freed of void nucleation catalysts exhibited a considerably reduced tendency for grain boundary cracking during creep, and increased stress-rupture life.

Download or read book Grain Boundary Cracking in Metals Under Stress at Elevated Temperatures written by JACK. BRETT and published by . This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the effect of purification and of a number of metal and oxide additions upon the occurrence of intergranular cracking in brass, Cu, Ni, Ti and Zr under t nsion at elevated temperatur s. Purificatio by a variety of means inhibited in ergranular cracking in brass, Cu, and Ni. Zr additions also decreased the frequency of grain boundary cracks in brass and Cu, while Al2O3 additions increased the number of cracks. Under a wide variety of conditions, Ti and Zr of commercial purity were immune to grain boundary cracks and intergranular fracture. A few experiments re performed to demonstrate t e parallel effect of impurities and additions upon the nucleation of voids during diffusion; the initiation of grain boundary cracks during creep; the mechanism of crack nucleation by vacancy condensation is discussed (Aut or).
Download or read book Perspectives in Creep Fracture written by M. F. Ashby and published by Elsevier. This book was released on 2014-05-23 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perspectives in Creep Fracture is a collection of studies that covers the advances in the analysis of the mechanisms involved in the process of creep fracture. The book presents nine articles that present data and discuss the theoretical advancement in the field. The text first covers the mechanisms leading to fracture in metals and ceramics, and then proceeds to tackling the problem of the nucleation of creep damage. Next, the book details the models for the growth of cracks and voids by diffusion and by plastic processes. The next two chapters deal with the creep fracture of ceramics. In the eighth chapters, the text examines the development and propagation of creep cracks. The last chapter details the theory involved in the propagation of cracks by cavitation. The book will be of great interest to researchers and practitioners of materials engineering, metallurgy, and other fields involved in fracture mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: * Numerous line drawings with consistent format and units allow easy comparison of the behavior of a very wide range of materials * Transmission electron micrographs provide a direct insight in the basic microstructure of metals deforming at high temperatures * Extensive literature review of over 1000 references provide an excellent reference document, and a very balanced discussionUnderstanding the strength of materials at a range of temperatures is critically important to a huge number of researchers and practitioners from a wide range of fields and industry sectors including metallurgists, industrial designers, aerospace R&D personnel, and structural engineers. The most up-to date and comprehensive book in the field, Fundamentals of Creep in Metals and Alloys discusses the fundamentals of time-dependent plasticity or creep plasticity in metals, alloys and metallic compounds. This is the first book of its kind that provides broad coverage of a range of materials not just a sub-group such as metallic compounds, superalloys or crystals. As such it presents the most balanced view of creep for all materials scientists. The theory of all of these phenomena are extensively reviewed and analysed in view of an extensive bibliography that includes the most recent publications in the field. All sections of the book have undergone extensive peer review and therefore the reader can be sure they have access to the most up-to-date research, fully interrogated, from the world's leading investigators.· Numerous line drawings with consistent format and units allow easy comparison of the behavior of a very wide range of materials· Transmission electron micrographs provide a direct insight in the basic microstructure of metals deforming at high temperatures· Extensive literature review of over 1000 references provide an excellent reference document, and a very balanced discussion

This book was released on 1958 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis is given of the oscillatory motions of vehicles which traverse ascending and descending paths through the atmosphere at high speed. The specific case of a skip path is examined in detail, and this leads to a form of solution for the oscillatory motion which should recur over any trajectory. The distinguishing feature of this form is the appearance of the Bessel rather than the trigonometric function as the characteristic mode of oscillation.

Available in PDF, EPUB and Kindle. Book excerpt: The era of lean production and excellence in manufacturing, advancing with sustainable development, demands the rational utilization of raw materials and energy resources, adopting cleaner and environmentally-friendly industrial processes. In view of the new industrial revolution, through digital transformation, the exploitation of smart and sophisticated materials systems, the need of minimizing scrap and increasing efficiency, reliability and lifetime and, on the other hand, the pursuit of fuel economy and limitation of carbon footprint, are necessary conditions for the imminent growth in a highly competitive economy. Failure analysis is an interdisciplinary scientific topic, reflecting the opinions and interpretations coming from a systematic evidence-gathering procedure, embracing various important sectors, imparting knowledge, and substantiating improvement practices. The deep understanding of material/component role (e.g., rotating shaft, extrusion die, gas pipeline) and properties will be of central importance for fitness for purpose in certain industrial processes and applications. Finally, it is hoped and strongly believed that the accumulation of additional knowledge in the field of failure mechanisms and the adoption of the principles, philosophy, and deep understanding of failure analysis process approach will strongly promote the learning concept, as a continuously evolving process leading to personal and social progress and prosperity.
Download or read book Mechanical Behavior of Materials written by Thomas H. Courtney and published by Waveland Press. This book was released on 2005-12-16 with total page 750 pages. Available in PDF, EPUB and Kindle. Book excerpt: This outstanding text offers a comprehensive treatment of the principles of the mechanical behavior of materials. Appropriate for senior and graduate courses, it is distinguished by its focus on the relationship between macroscopic properties, material microstructure, and fundamental concepts of bonding and crystal structure. The current, second edition retains the original editions extensive coverage of nonmetallics while increasing coverage of ceramics, composites, and polymers that have emerged as structural materials in their own right and are now competitive with metals in many applications. It contains new case studies, includes solved example problems, and incorporates real-life examples. Because of the books extraordinary breadth and depth, adequate coverage of all of the material requires two full semesters of a typical three-credit course. Since most curricula do not have the luxury of allocating this amount of time to mechanical behavior of materials, the text has been designed so that material can be culled or deleted with ease. Instructors can select topics they wish to emphasize and are able to proceed at any level they consider appropriate.
