Special Interest Program (SIP) presentations are cutting-edge R&D and typically oral in nature, but all submitted publishable manuscripts will be included in the conference proceedings.


SPECIAL INTEREST PROGRAM

Sunday Afternoon

2:15–3:30 p.m.



SIP 1-1
Mechanical Properties for FEA Modeling—Part 1


Program Organizers
Bruce Lindsley, Hoeganaes Corporation
Virindra Warke, Entegris






This program will explore the need for PM mechanical property data to enable finite element analysis being conducted at OEM’s. Competing technologies have developed standard sets of data for a wide range of material grades and shared this data with end users and modeling companies. Equivalent data for powder metallurgy is not widely available or is limited to a select few materials and densities. As industry moves from empirical knowledge to simulation for new component development, PM is at risk to lose applications in the design phase. The current state of mechanical property needs will be explored with examples of PM modeling issues discussed.

SIP 2-1
Flow and Spreadability of Metal Powders–Part 1: Review of Prior Work


Program Organizers
W. Brian James, FAPMI, PMtech
Louis-Philippe Lefebvre, National Research Council Canada






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.

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.
