Available in PDF, EPUB and Kindle. Book excerpt: Austempered Ductile Cast Iron is emerging as an important engineering materials in recent years because of its excellent combination of mechanical properties such as high strength with good ductility, good fatigue strength and fracture toughness together with excellent wear resistance. These combinations of properties are achieved by the microstructure consisting of acicular ferrite and high carbon austenite. Refining of the ausferritic microstructure will further enhance the mechanical properties of ADI and the presence of proeutectoid ferrite in the microstructure will considerably improve the ductility of the material. Thus, the focus of this investigation was to develop nanostructured austempered ductile cast iron (ADI) consisting of proeutectoid ferrite, bainitic ferrite and high carbon austenite and to determine its microstructure-property relationships. Compact tension and cylindrical tensile test samples were prepared as per ASTM standards, subjected to various heat treatments and the mechanical tests including the tensile tests, plane strain fracture toughness tests, hardness tests were performed as per ASTM standards. Microstructures were characterized by optical metallography, X-ray diffraction, SEM and TEM. Nanostructured ADI was achieved by a unique heat treatment consisting of austenitization at a high temperature and subsequent plastic deformation at the same austenitizing temperature followed by austempering. The investigation also examined the effect of cryogenic treatment, effect of intercritical austenitizing followed by single and two step austempering, effect of high temperature plastic deformation on the microstructure and mechanical properties of the low alloyed ductile cast iron. The mechanical and thermal stability of the austenite was also investigated. An analytical model has been developed to understand the crack growth process associated with the stress induced transformation of retained austenite to martensite.

Download or read book Micromachining with Nanostructured Cutting Tools written by Mark J. Jackson and published by Springer Science & Business Media. This book was released on 2012-09-21 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress-reducing defects and subsequent microcracks are a central focus during micromachining processes. After establishing the central process of micromachining Micromachining with Nanostructured Cutting Tools explains the underlying theories that describe chip formation and applies elementary cutting theory to machining at the microscale. Divided into three parts, the second half of Micromachining with Nanostructured Cutting Tools develops on this introduction; explaining how frictional interactions between uncoated and micro tools coated with nanostructered coatings can be characterized by using the elementary micromachining theories that were initially developed for machining at the macroscale. Shaw’s methods for calculating temperatures at the interaction zone and Merchant’s methods for calculating mechanical interactions are well described and justified for machining steel in both the dry and wet states. Finally, the further development and use of micro tools coated with thin-film nanostructured diamonds are shown. Micromachining with Nanostructured Cutting Tools is a resource for engineers and scientists working in this new field of micro and nanotechnology. The explanations of how to characterize, apply and adapt traditional approaches of understanding the mechanics of practical machining to the machining of microproducts using nanostructured tools provides a reliable reference for researchers and practitioners alike.

Download or read book Bainite in Steels written by H.K.D.H. Bhadeshia and published by CRC Press. This book was released on 2019-04-15 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third edition of the book, much expanded to include and incorporate important developments in the subject over the last fifteen years. The book represents a comprehensive treatise on all aspects of the bainite transformation, from the choreography of atoms during the phase change to length scales that are typical of engineering applications. The alloy design that emerges from this explains the role of solute additions, and the pernicious effects of impurities such as hydrogen. The picture presented is self-consistent and therefore is able to guide the reader on the exploitation of theory to the design of some of the most exciting steels, including the world’s first bulk nanostructured metal.

This book was released on 2020-04-08 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallurgy is a field of material science and engineering that studies the chemical and physical behavior of metallic elements, intermetallic compounds, and their mixtures, which are called alloys. These metals are widely used in this kind of engineering because they have unique combinations of mechanical properties (strength, toughness, and ductility) as well as special physical characteristics (thermal and electrical conductivity), which cannot be achieved with other materials. In addition to thousands of traditional alloys, many exciting new materials are under development for modern engineering applications. Metallurgical engineering is an area concerned extracting minerals from raw materials and developing, producing, and using mineral materials. It is based on the principles of science and engineering, and can be divided into mining processes, which are concerned with the extraction of metals from their ores to make refined alloys, and physical metallurgy, which includes the fabrication, alloying, heat treatment, joining and welding, corrosion protection, and different testing methods of metals. Conventional metal forming/shaping techniques include casting and forging, which remains an important processing route. Electrodeposition is one of the most used methods for metal and metallic alloy film preparation in many technological processes. Alloy metal coatings offer a wider range of properties than those obtained by a single metal film and can be applied to improve the properties of the substrate/coating system. This book covers a wide range of topics related to recent advancements in metallurgical engineering and electrodeposition such as metallurgy forming, structure, microstructure properties, testing and characterizations, and electrodeposition techniques. It also highlights the progress of metallurgical engineering, the ferrous and non-ferrous materials industries, and the electrodeposition of nanomaterials and composites.

Download or read book Bainite and Martensite written by Carlos Garcia-Mateo and published by MDPI. This book was released on 2020-05-27 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microstructures of both martensite and bainite, although sharing some common features, depict a plethora of subtle differences that made them unique when studied in further detail. Tailoring the final properties of a microstructure based on one or the other as well as in combination with others and exploring more sophisticated concepts, such as Q&P and nanostructured bainite, are the topics which are the focus of research around the world. In understanding the key microstructural parameters controlling the final properties as well as definition of adequate process parameters to attain the desired microstructures requires that a proper understanding of the mechanism ruling their transformation and a detailed characterization first be acheived. The development of new and powerful scientific techniques and equipment (EBSD, APT, HRTEM, etc.) allow us to gain fundamental insights that help to establish some of the principles by which those microstructures are known. The developments accompanying such findings lead to further developments and intensive research providing the required metallurgical support.
