Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Ferrous powder metallurgy (PM) makes up the majority of powder metallurgy products with regard to tonnage. Improving performance is the main trend for pressed and sintered parts, in particular the introduction of cost-effective alloy elements such as Cr and Mn. Furthermore, much can be gained in ferrous PM by elaborate secondary operations. In metal injection moulding (MIM) products, there is a clear trend towards increasingly complex shapes and microsized parts. PM tool steels offer a much finer and fully isotropic microstructure compared to their wrought counterparts and the carbide content may be much higher, resulting in excellent application properties.

Book excerpt: Powder Metallurgy discusses the production of metal powders and other materials made from it. It defines the meaning of metal powders with some illustrations. The book also identifies the processes similar between the production of metal powder and ceramic products. The technology involved and the variation in the process of metallurgy are covered in some chapters of the book. The book enumerates certain advantages in using powder metallurgy over other processes. Methods such as the reduction of the oxides of metals, electrolysis, thermal dissociation, and chemical disintegration are explained. The origin and improvement made on the method are discussed in detail. The goods created using the process are also explained, as well as the types of metals that are being used. A chapter of the book focuses on the flaws of powder metallurgy. The book will provide useful information to metal smiths, chemists, students, and researchers in the field of chemistry.

Book excerpt: Powder metallurgy, commonly designated by its initial letters asPM or PM, may be defined as the production of useful artefacts from metal powder without passing through the molten state. This introductory text examines the processes by which these powders are produced, and explores their behaviour in the subsequent consolidation stages.
Download or read book Manganese in Powder Metallurgy Steels written by Andrej Šalak and published by Springer Science & Business Media. This book was released on 2012-07-13 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work in three parts presents a summary of the sintered manganese steel properties from 1948 to 2011 involving processing conditions and other characteristics. In the first and third part are given results attained by the authors based on their finding that manganese (cheapest element) during sintering evaporates and by this the vapour cleans the sintering atmospheres from humidity. The second part presents other positive properties of manganese steels in spite of the doubt of oxidation of manganese during sintering and by this excluding the sintering manganese steels what hinderd the use of manganese in production of sintered parts. All results confirm that only manganese vapour according to finding of the authors ensures effective sintering of manganese steels and parts independently on the authors mind. It follows finally from the work that manganese is possible to use for alloying of powder steels sintered also in practice in H/N atmospheres with low purity and also in pure nitrogen - cheaper than hydrogen without some of the associated problems. Current trends in the field are also presented to the reader.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: On-demand operators have more risk in their operating environments and receive less oversight from FAA. For example, one on-demand operator we visited flew dozens of flights daily during the summer to take tourists to glaciers on which the aircraft landed and took off on skis. This operator flies 17 aircraft and was inspected 8 times by FAA in 2008. In contrast, a Part 121 operator with 10 aircraft, overseen by the same FAA oversight office, received 199 inspections in 2008. Industry and the National Transportation Safety Board (NTSB) have made recommendations to strengthen on-demand regulations. While FAA has made efforts to improve safety and adapt its oversight to the increased complexity of industry operations, it has not taken substantive action to address these recommendations. Further, FAA does not effectively target inspections to higher-risk on-demand operators. The number of fatalities from on-demand operations makes it imperative that FAA take action to address three issues we identified as it plans regulatory and oversight changes for the growing on-demand operator industry.
