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
Annotation Examines the factors that contribute to overall steel deformation problems. The 27 articles address the effect of materials and processing, the measurement and prediction of residual stress and distortion, and residual stress formation in the shaping of materials, during hardening processes, and during manufacturing processes. Some of the topics are the stability and relaxation behavior of macro and micro residual stresses, stress determination in coatings, the effects of process equipment design, the application of metallo- thermo-mechanic to quenching, inducing compressive stresses through controlled shot peening, and the origin and assessment of residual stresses during welding and brazing.

Book Description
Metal powders are just a tiny fraction of the global metals industry, yet they play a key role in such high-profile sectors as cars and consumer electronics. The global value of metal powder consumption has risen since 2000 to over $3.7 billion from under $3 billion. Part of this increase is due to recently escalating primary metal prices. The increase in overall tonnage shipped is in the order of 20%. This fourth edition of Metal Powders: A Global Survey of Production, Applications & Markets 2001 – 2010 has been completely revised to include the most up-to-date information available, in order to provide a coherent picture of the development and status of the metal powder industry. The report is an overview of the production, applications and markets for metal and alloy powders. The market data is presented primarily in terms of tonnages because of the widely different prices of these powders. Markets for each of the metal powder types are discussed in terms of the major application areas. Market data for the main geographical areas are based on industry statistics, supplemented by company annual reports and by private estimates. Other data and forecasts have been compiled from literature surveys, personal visits and telephone interviews.* Review of metal and alloy powder consumption by type of powder and by geographical area* Market forecasts to 2010* Technical overview of metal powder production* Worldwide review of major producers

Book Description
The handbook provides design engineers with up-to-date information about the many aspects of forging including descriptions of important developments made more recently by industry and/or government. The handbook describes suitable measures for in-process quality control and quality assurance, summarizes relationships between forging practices and important mechanical properties and compares various forging devices to aid in equipment selection. Attention is also given to describing practices for relatively new materials and emerging forging practices. (Modified author abstract).
