High-performance permanent magnets: The influence of rare earths and the development of alternative materials

Rare earth permanent magnets have, for the past forty years dominated the higher performance magnetic devices market. However, the availability of raw materials globally is proving a risk to market stability for this important class of magnet.

Material scientists have the opportunity to address this issue and the use of elements such as nitrogen, nanostructured materials and metastable materials, is now being explored. Dr Sim Narasimhan reviews the developments and the challenges facing these alternative materials.

Optimising iron-based PM self-lubricating bearings: The influence of graphite

Sintered self-lubricating bearings are typically made from bronze alloys, however, for less demanding applications, iron-copper combinations offer a low-cost alternative. As a relatively high level of final porosity is required, a careful design of base powders and processing is necessary to achieve desirable properties in both the green and sintered states.

In this experimental study, Matteo Zanon of Pometon SpA presents existing and newly developed iron-copper PM solutions to address issues arising from the addition of graphite, with a special focus on the influence of natural graphite granulometry.

Innovation drives success in the Japan Powder Metallurgy Association’s 2017 awards

The winners of this year’s Japan Powder Metallurgy Association (JPMA) PM component awards highlight the continuing developments being made to further expand the range of applications for our technology.

The number of components recognised for their innovation suggests that there continues to be the potential for new applications in the automotive sector, particularly in the latest generation of highly efficient international combustion engines and automatic gearboxes.

Euro PM2017: Hot Isostatic Pressing for enhanced performance and demanding applications

A technical session at the Euro PM2017 congress, held in Milan, Italy, October 1-5, 2017, identified a number of process developments in Hot Isostatic Pressing (HIP) that address the need for high performance components in demanding applications.

In this report, Dr David Whittaker reviews three papers from the session which highlight the processing of the superalloy Astroloy, study the influence of isostatic pressure on phase transformations and suggest the use of glass container encapsulation to improve density distribution in stainless steel components.

POWDERMET2017: Improved dimensional control in PM iron-copper-carbon materials

Iron-copper-carbon is one of the most widely used materials in Powder Metallurgy component production thanks to its low cost and high mechanical and metallurgical properties. However, there are a number of issues which can result in the need for additional sizing and machining operations.

Papers presented at the POWDERMET2017 Conference, Las Vegas, June 13-16, 2017, discussed options to improve dimensional control and limit post processing operations. Dr David Whittaker reviews a selection of these papers.

Powder Metallurgy: The original net-shape production process

Powder Metallurgy components are relied upon by a wide variety of manufacturing industries, from automotive to power tools, household appliances, chemical engineering, filtration and more.

The main reason for the technology’s success is its cost-effectiveness at producing high volumes of net-shape components, combined with its ability to allow the manufacture of products that, because of the production processes, simply cannot be manufactured by other methods.

To discover more about how the technology has revolutionised component production, browse our Introduction to Powder Metallurgy.
