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
Powder metallurgy (PM) is a popular metal forming technology used to produce dense and precision components. Different powder and component forming routes can be used to create an end product with specific properties for a particular application or industry. Advances in powder metallurgy explores a range of materials and techniques used for powder metallurgy and the use of this technology across a variety of application areas.Part one discusses the forming and shaping of metal powders and includes chapters on atomisation techniques, electrolysis and plasma synthesis of metallic nanopowders. Part two goes on to highlight specific materials and their properties including advanced powdered steel alloys, porous metals and titanium alloys. Part three reviews the manufacture and densification of PM components and explores joining techniques, process optimisation in powder component manufacturing and non-destructive evaluation of PM parts. Finally, part four focusses on the applications of PM in the automotive industry and the use of PM in the production of cutting tools and biomaterials.Advances in powder metallurgy is a standard reference for structural engineers and component manufacturers in the metal forming industry, professionals working in industries that use PM components and academics with a research interest in the field. - Discusses the forming and shaping of metal powders and includes chapters on atomisation techniques - Highlights specific materials and their properties including advanced powdered steel alloys, porous metals and titanium alloys - Reviews the manufacture and densification of PM components and explores joining techniques

Book Description
Because of the position of ferrous powder metallurgy, the author deals with the theoretical fundamentals and technical and technological aspects of the current state of knowledge in ferrous powder metallurgy so that special attention may be given to all factors influencing parts and materials with the required properties, form and dimensions, stressing their higher economic efficiency. The book also shows the extensive possibilities for further development of ferrous powder metallurgy and should therefore contribute to increasing the level of general and detailed knowledge of experts working in this area and should help in transition from fabrication of parts by conventional methods with all typical economic and ecological shortcomings to fabrication by powder metallurgy methods.

Book Description
Hard machining is a relatively recent technology that can be defined as a machining operation, using tools with geometrically defined cutting edges, of a work piece that has hardness values typically in the 45-70HRc range. This operation always presents the challenge of selecting a cutting tool insert that facilitates high-precision machining of the component, but it presents several advantages when compared with the traditional methodology based in finish grinding operations after heat treatment of work pieces. Machining of Hard Materials aims to provide the reader with the fundamentals and recent advances in the field of hard machining of materials. All the chapters are written by international experts in this important field of research. They cover topics such as: • advanced cutting tools for the machining of hard materials; • the mechanics of cutting and chip formation; • surface integrity; • modelling and simulation; and • computational methods and optimization. Machining of Hard Materials can serve as a useful reference for academics, manufacturing and materials researchers, manufacturing and mechanical engineers, and professionals in machining and related industries. It can also be used as a text for advanced undergraduate or postgraduate students studying mechanical engineering, manufacturing, or materials.

Book Description
All of the critical technical aspects of gear materials technology are addressed in this new reference work. Gear Materials, Properties, and Manufacture is intended for gear metallurgists and materials specialists, manufacturing engineers, lubrication technologists, and analysts concerned with gear failures who seek a better understanding of gear performance and gear life. This volume complements other gear texts that emphasize the design, geometry, and theory of gears. The coverage begins with an overview of the various types of gears used, important gear terminology, applied stresses and strength requirements associated with gears, and lubrication and wear. This is followed by in-depth treatment of metallic (ferrous and nonferrous alloys) and plastic gear materials. Emphasis is on the properties of carburized steels, the material of choice for high-performance power transmission gearing.
