Book Description
The machinability of powder metallurgy steels is poorer compared with wrought steels of appropriate composition and/or mechanical [properties. The reason for it is a larger number of material and processing variables affecting the final properties of a sintered material. Therefore the machining of powder metallurgy (PM) steels is a permanent subject of investigation and practice. The aim of the book is to make on the basis of present knowledge an overview of all interacting factors in machining process including those applied for the improvement of the machinability. There are the properties of basic plain iron and alloyed powders, various additions, compaction and sintering conditions. Effect of porosity, individual alloying elements and microstructure character is considered. The description of the basic machining processes with their characteristics and with the characteristics of the tool geometry belongs to the mentioned factors. For the improvement of machinability of PM steels different machining aids, as S, MnS, MoS2 and other are frequently used and their chemical and physical characteristics are given. The effect of various machining aids used on machinability of sintered plain iron, iron-carbon and of steels alloyed with Cu, Ni, Mo, Cr, Mn including powder forged steels with very different mechanical properties and very different microstructures is analysed and summarized. The high-speed steel, hardmetal and other tools with their geometry as the part of the cutting process are described in relation to the sintered powder materials. The recommendations for machining of various steels enclose the present knowledge about the machinability of powder metallurgy steels.

Book Description
Much research has been carried out and a lot of progress has been made towards the use of composite materials in a wide field of tribological applications. In recent years studies have been made to determine to what degree phenomena governing the tribological performance of composites can be generalized and to consolidate interdisciplinary information for polymer-, metal- and ceramic matrix composites.The importance of promoting better knowledge in the areas of friction, lubrication and wear, in general, is demonstrated by the contents of this volume. It covers a wide range of subjects extending from fundamental research on the tribological characteristics of various multi-phase materials up to final applications of composites in wear loaded, technical components. Besides the emphasis on composites tribology, the great practical aspect of the field in many industrial applications is also reviewed by authors who are engaged in applied research as well as those in more academic activities. The articles in this volume will facilitate both researchers and mechanical designers in their work towards a set of predictive, materials engineering-related models for a more reliable use of composites as tribo-materials.Through the study of, and observation of, the tribology of sensibly formulated composite systems may emerge a clear and more profound understanding of the subject of tribology. In this sense, this book offers a major and critical evaluation of the state of understanding of the principles of tribology and its ability to serve the practical and commercial needs of this technology generally, and particularly in the context of composite systems.

Book Description
Low shear polymer powder processing provides unique solutions to many processing problems and offers a set of production techniques, frequently un-paralleled by other production methods. In recent years there has been increased interest in this field but no comprehensive review of the subject has been available until now. In this book, a team of experts have taken the novel approach of treating several processing techniques, such as compacted powder sintering, rotational moulding, powder coating, ram extrusion, and compression moulding, as diverse implementations of a single technology. The first chapters deal with the scientific and engineering fundamentals shared by various polymer powder processing techniques, and are followed by a detailed examination of each technique and some special effects. Polymer Powder Technology will prove invaluable to technologists, plastics and materials engineers, researchers and students working with various aspects of particulate polymer processing.

Book Description
Because of the sheer size of the plastics industry, the title Developments in Plastics Technology now covers an incredibly wide range of subjects or topics. No single volume can survey the whole field in any depth and so what follows is therefore a series of chapters on selected topics. The topics were selected by us, the editors, because of their immediate relevance to the plastics industry. When one considers the materials produced and used by the modern plastics industry, there is a tendency to think of the commodity thermoplastics (such as poly(vinyl chloride) or polyethylene); the thermosetting materials are largely ignored. Because of this attitude we are very pleased to include in this volume a chapter which deals with the processing of a thermosetting material, i.e. the pultrusion of glass reinforced polyester. The extrusion of plastics is, of course, a very important subject but an aspect which is often overlooked is the need to remove volatile matter during processing: for this reason we have included a chapter on devolatilisation. Current industrial practice is towards materials modification and this attitude is reflected in the chapters on the transformation of ethylene vinyl acetate polymers and the use of wollastonite in two important thermoplastics. When assessing the performance of materials, there is a tendency to concentrate on short-term mechanical tests and ignore such topics as fatigue and longer-term testing. We are therefore very pleased to include a chapter on this subject.

Book Description
The powder forming process is an extremely effective method of manufacturing structural metal components with high-dimensional accuracy on a mass production basis. The process is applicable to nearly all industry sectors. It offers competitive engineering solutions in terms of technical performance and manufacturing costs. For these reasons, powder metallurgy is developing faster than other metal forming technology. Computational Plasticity in Powder Forming Proceses takes a specific look at the application of computer-aided engineering in modern powder forming technologies, with particular attention given to the Finite Element Method (FEM). FEM analysis provides detailed information on conditions within the processed material, which is often more complete than can be obtained even from elaborate physical experiments, and the numerical simulation makes it possible to examine a range of designs, or operating conditions economically.* Describes the mechanical behavior of powder materials using classical and modern constitutive theories.* Devoted to the application of adaptive FEM strategy in the analysis of powder forming processes.* 2D and 3D numerical modeling of powder forming processes are presented, using advanced plasticity models.

Book Description
The manufacture and use of the powders of non-ferrous metals has been taking place for many years in what was previously Soviet Russia, and a huge amount of knowledge and experience has built up in that country over the last forty years or so. Although accounts of the topic have been published in the Russian language, no English language account has existed until now.Six prominent academics and industrialists from the Ukraine and Russia have produced this highly-detailed account which covers the classification, manufacturing methods, treatment and properties of the non-ferrous metals ( aluminium, titanium, magnesium, copper, nickel, cobalt, zinc, cadmium, lead, tin, bismuth, noble metals and earth metals).The result is a formidable reference source for those in all aspects of the metal powder industry. - Covers the manufacturing methods, properties and importance of the following metals: aluminium, titanium, magnesium, copper, nickel, cobalt, zinc, cadmium, noble metals, rare earth metals, lead, tin and bismuth - Expert Russian team of authors, all very experienced - English translation and update of book previously published in Russian
