In addition to more than 35 pages of news from the Powder Metallurgy industry, the 88 page Spring 2017 issue of Powder Metallurgy Review magazine (Vol. 6 No. 1) includes the following articles and special features:
The changing landscape of carbonyl iron and nickel powder production
Until recently, much of the global production of carbonyl metal powder was centred on manufacturers in Europe and North America. Although China has produced these powders since the 1960s, the last ten years or so has seen a rapid increase in the volume of both carbonyl nickel and carbonyl iron powders produced in this region.
In this report, Jun Shu and Lou Koehler describe the production processes and look at the changing landscape of carbonyl metal powder production.
Graphite and its applications in the Powder Metallurgy industry
With its unique structure and properties, graphite is a versatile raw material used in a wide range of industries. Graphite offers excellent electrical and thermal conductivity as well as outstanding lubrication properties and high resistance to temperature and oxidation. In the Powder Metallurgy industry, graphite is an essential additive in metal powder mixes for the production of sintered parts.
In this article, Dr Robert Feher, R&D Director at Graphit Kropfmühl GmbH, Germany, reviews the use of graphite in the Powder Metallurgy process as well as its various applications.
Innovation recognised in Japan’s PM award winning parts, materials and processes
The winners of the Japan Powder Metallurgy Association’s (JPMA) 2016 Powder Metallurgy Awards showcase the continuing developments being made to further expand the range of applications for Powder Metallurgy.
The winners showcase innovations not only in component design, but also in new materials and advanced manufacturing processes.
Hot Isostatic Pressing at World PM2016: Developments in production and processing
Papers in the three technical sessions dedicated to Hot Isostatic Pressing technology at the World PM2016 Congress, held in Hamburg, Germany, 9-13 October 2016, addressed developments in production techniques and processing issues.
In this article, Dr David Whittaker reviews three papers from these sessions that describe a novel capsule-free HIP method, the near net shape HIP fabrication of an impeller and the phase transformation under isostatic pressure in HIP.
World PM2016: Developments in hardmetal processes and applications
Developments in the processing and application of hardmetals were the subject of a number of papers at the World PM2016 Congress, held in Hamburg, Germany, 9-13 October 2016. In this review Dr David Whittaker highlights two presentations that discuss the use of Electric Resistance Sintering and Spark Plasma Sintering to process hardmetals.
A further two presentations look at the development of a novel binder phase and the influence of numerous factors on the wear and fracture mechanisms of drill bits during drilling of reinforced concrete.
