Join Dr. Chris Freemantle, Pilot Tools, in this case study as he explores the causes of the behaviour differences when using recycled powders, the interconnectedness of slurry and powder rheology, and the potential impact that the use of recycled powders can have on a manufacturing process. Ultimately, this case study demonstrates the power and utility of powder rheology, a technique yet to be fully embraced by the powder metallurgy industry.
