Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes results of several areas of research dealing with mechanical alloying of materials having potential structural use. The areas involve modeling of the process, synthesis of unique materials via mechanical alloying and consolidation of mechanically alloyed products. The latter area is one receiving most current attention as consolidation involves high temperatures and (usually) pressures. This can lead to a 'loss' of the unique structures produced by mechanical alloying. Thus, consolidation studies attempt to produce fully dense material maintaining many of the desirable properties manifested by mechanically alloyed powders.

Download or read book Mechanical Alloying written by Li Lü and published by Springer Science & Business Media. This book was released on 1997-11-30 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical alloying (or mechanical milling) was invented in the 1970's as a method to develop dispersion-strengthened high temperature alloys with unique properties. With the discovery of formation of amorphous alloys using this technique, it has received new research interest in developing different material systems. Potential applications of this technique have been demonstrated in different areas of materials research. This book is intended as an introduction to mechanical alloying technique used in difference areas. This book contains basic information on the preparation of materials using the mechanical alloying technique. It is useful not only to undergraduate and post-graduate students, but also to scientists and engineers who wish to gain some understanding on the basic process and mechanisms of the process. The book begins with a brief introduction to provide a historical background understanding to the development of the mechanical alloying process. The experimental set-up in the alloying process is important. Currently there are different types of ball mills available. Some of them are specially designed for mechanical alloying process. Since the resultant materials are milling intensity and milling temperature dependent, ball mills should be carefully selected in order to obtain the desired materials and structures. This is discussed in chapter 2. The actual mechanical alloying process is being considered in Chapter 3. As it is essential to understand the use of processing control agents, the physical properties of some commonly used processing control agents are listed.

Available in PDF, EPUB and Kindle. Book excerpt: Relationships among the synthesis, processing, structure and properties of materials generated through mechanical alloying (MA) or mechanosynthesis are described. Several materials classes: cermets, particulate metal matrix composites (MMC), and tungsten heavy alloys (WHA) have been produced, and their properties and structures evaluated. Niobium carbide and tungsten, carbide cermets can be conveniently generated either through room temperature synthesis (NbC cermets) or by room temperature milling followed by elevated temperature exposure (WC cermets). Cermet microstructures following consolidation are fine, and the materials demonstrate exceptional hardnesses albeit their fracture toughnesses are generally low. Al based MMC can be synthesized similarly. The composites we have studied utilize aluminum carbide as a reinforcement. The yield strengths of these MMC are approximately twice those of high strength aerospace Al alloys. Noncrystalline WHA can be generated via MA. During consolidation, these alloys are prone to crystallization. Nonetheless, because of their fine structure the crystalline products manifest high hardnesses relative to conventional WHA. Current efforts are focusing on retaining the noncrystalline phase during consolidation so as to produce materials having particularly desirable mechanical properties.
Book Synopsis Mechanical Alloying by : Joan-Josep Suñol
Download or read book Mechanical Alloying written by Joan-Josep Suñol and published by Mdpi AG. This book was released on 2021-09-29 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical alloying is a technique of producing alloys and compounds that permits the development of metastable materials (with amorphous or nanocrystalline microstructure) or the fabrication of solid solutions with extended solubility. The elements or compounds to be mixed (usually as powders) are introduced in jars usually under a controlled atmosphere. Regarding the scope of this book, advanced materials have been developed by mechanical alloying: Fe-X-B-Cu (X = Nb, NiZr) nanocrystalline alloys, mixtures of the binary Fe-Mn and Fe-Cr alloys with chromium and manganese nitrides, Mn-Al-Co and Mn-Fe alloys, non-equiatomic refractory high-entropy alloys, nanocrystalline Fe-Cr steels, nanaocrystalline Mn-Co-Fe-Ge-Si alloys, Al-Y2O3 nanocomposite, and hydride-forming alloys. Likewise, production conditions and ulterior treatments can provide readers interesting ideas about the procedure to produce alloys with specific microstructure and functional behavior (mechanical, magnetic, corrosion resistance, hydrogen storage, magnetocaloric effect, wastewater treatment, and so on). As an example, to obtain the improvement in the functional properties of the alloys and compounds, sometimes controlled annealing is needed (annealing provokes the relaxation of the mechanical-induced strain). Furthermore, the powders can be consolidated (press, spark plasma sintering, and microwave sintering) to obtain bulk materials.

Download or read book High-Entropy Alloys written by Anil Kumar and published by Walter de Gruyter GmbH & Co KG. This book was released on 2023-03-20 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an analysis of the state-of-the-art in high entropy alloys (HEA). In order to increase the qualities of an alloy, one major element is typically chosen and other elements are added to it in small amounts. In order to create multi-component alloys without a single major element, Professor J.W. Yeh described a novel method of alloy design in 2004. This method involved mixing elements in equiatomic or nearly equiatomic proportions. HEAs have a wide range of structural and physical properties and may find use in various applications. HEAs are intended to have high configurational entropy. The fundamental information now known in the subject, the range of different alloy systems and the features that have been investigated so far, the current major study fields, and the technological applications are presented in this book. Includes high entropy alloy fabrication and phase development. Discusses thermodynamic design criteria to develop HEAs. Covers the HEAs functioning characteristics. Compares the different processing routes used for the synthesis of HEAs

Download or read book Non-equilibrium Processing of Materials written by C. Suryanarayana and published by Elsevier. This book was released on 1999-07-22 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid technological developments during the later half of the 20th century have demanded materials that are stronger, capable of use at much higher temperatures, more corrosion-resistant, and much less expensive than those currently used. These demands become even more significant on the threshold of the new century and the millennium. Significant improvements in properties can only be achieved by processing the materials under far-from-equilibrium (or non-equilibrium) conditions. Several new processing technologies have been developed during the past few decades including, rapid solidification, spray forming, mechanical alloying, ion mixing, vapor deposition, laser processing and plasma processing. Remarkable advances have been made in recent years in the science and technology of these processes used to synthesize, characterize, and apply these materials processed under non-equilibrium conditions. Some of these techniques have evolved from laboratory curiosity to commercial-scale manufacturing in just a few years. In other cases, industrial necessity prompted development of the technology, and the science followed later. The chapters in this book have been written by people who are world-recognized experts in their respective fields. Each chapter describes the principles, processing techniques, special features of the materials produced, and their applications. An extensive list of references is provided at the end of each chapter that will facilitate location of additional information on specific aspects of any technique.
