Improvement in Precision/Accuracy/Variation Control

Program Organizers:
Roland T. Warzel, III, North American Höganäs Co.
John Engquist, FAPMI, JENS Solutions LLC
Roger Lawcock, FAPMI, Stackpole International

The 2017 Powder Metallurgy (PM) Industry Roadmap outlined four focus areas of technology priority to allow for continued growth of the PM industry.  As competing technologies such as castings, forgings and stampings continue to improve their capabilities, PM needs to continue to take advantage of its near net shape capability and further improve dimensional capability. Improvement in dimensional capability through material and process improvements will allow for decreased cost of quality and opening of new business opportunities.

Alan Lawley Memorial Symposium

Program Organizer:
Christopher T. Schade, Hoeganaes Corporation

A long-time friend and supporter of PM technology and the industry, Professor Alan Lawley, FAPMI, (1933–2017) made significant contributions to research and development in PM and particulate materials and guided the professional development of undergraduate and graduate PM students, many of whom are working in the industry today. His PM teachings, research, and consulting activities resulted in co-authoring three MPIF Outstanding Technical Paper Award recipients and the monograph “Atomization: The Production of Metal Powders.” This symposium will be a reflection of the technical advancements and outgrowth from this research.

Flow and Spreadability of Metal Powders

Program Organizers:
W. Brian James, FAPMI, PMtech
Louis-Philippe Lefebvre, National Reseach Council

Flow is an important attribute for powders used for pressing and sintering. It is also a key characteristic for powders that are used for additive manufacturing via powder-bed-fusion and binder-jet processing. Standardized tests such as flow through the Hall flowmeter funnel have been used for many years and Carney flow has been used for non-free-flowing metal powders. Newer tests using rotating drums and powder rheometers have also been used to measure powder properties. This SIP will review prior work in this area and present the results of interlaboratory blind tests to determine the discriminating capability and the repeatability and reproducibility of these newer test methods.
