PowderMet 2011 Preview: Special Interest Programs address opportunities and challenges for PM

San Francisco plays host to this year’s

PowderMet Conference and Exhibition

The city of San Francisco is hosting the 2011 PowderMet conference and exhibition later this month and a full programme is expected to attract industry experts from around the world.

A highlight of the event is a series of Special Interest Programs focused on specific applications or processes for Powder Metallurgy components. In this short preview we look at the four Special Interest Programs scheduled to run during the event.  

The PowderMet 2011 International Conference on Powder Metallurgy and Particulate Materials is organised by the Metal Powder Industries Federation (MPIF), and takes place from Wednesday May 18 – Saturday May 21.

PM Materials for Alternative Energy

The powder metallurgy process, being of net shape with minimal waste, has attracted a number of industries such as fuel cells, solar energy, photovoltaics and batteries. This program addresses the advancements PM has made in these industries. Presentations scheduled are:

Magnet Materials and Applications

Devices based on magnetic materials are used in automotive components and in other applications ranging from washing machines and hand tools to biomedical machinery. There is an increasing need to make these magnet devices with higher performance, compact size, lightweight, and at low cost.

Such size and weight reduction could be achieved through the innovations in materials, processing, and new design approaches. This program presents an overview of magnet materials and applications along with the challenges and opportunities for the PM community to improve these devices. Presentations scheduled are:

Tribology

Tribology is the science of interacting surfaces in relative motion, including the understanding of friction, lubrication, and wear. Tribological behaviour is an integral part of the powder metallurgy process, i.e., interaction between individual powder particles, powder particles and die walls, and mating PM surfaces in high-performance applications.

This programme includes discussion of the friction and wear behaviour of sintered parts, quantifying surfaces of PM parts in regards to porosity, design aspects for wear resistance, post-processing technologies to improve wear behaviour of PM parts, and the effect of tribological variables on compaction. Presentations scheduled are:

Quantifying Surfaces on PM Parts

Edward P. Becker, GM Powertrain

Design Aspects of Powder Metal Gear Design: Macro and Micro Geometry Considerations

Anders Flodin, Höganäs AB

AFM Investigation of Powder-Surface Forces

Steven R. Schmid, Michael A. Giordano, University of Notre Dame

Hardfacing by Powder Technologies as a Means to Improve Abrasive/ Adhesive Wear and Corrosion Resistance

Senad Dizdar, Höganäs AB

Effect of Tribological Variables on Compaction Modeling

Hossein Kashani Zadeh, Queens University & J. Jeswiet, Australian National University

Sinter Hardening and Leaner/ Economic Powders

Sinter hardening is a cost-effective strategy that eliminates some of the steps involved with heat treating of PM steels. Initially, sinter hardenable powders contained significant concentrations of alloying elements to accommodate the slow cooling rates of “conventional” sintering furnaces. Nevertheless, recent optimisation work in terms of thermal profile in the cooling section of sintering furnaces as well as alloy design and sinter-hardenability characterisation has opened up new possibilities for sinter hardening both in terms of flexibility and cost savings.

The presentations grouped in this program will put forward these new developments in the perspective of real-life applications and future trends. Presentations scheduled are:

Sinter Hardening–an Historical Perspective

W. Brian James, Hoeganaes Corporation
