This webinar reviewed the use of these low-shear avalanche (“drum”) rheometers for characterizing the flow of metal powders. Dr. Dave van der Wiel, NSL's Director of Technology Development, discussed several data sets from this technique, with an emphasis on parametric effects and statistical analysis of rheometer data. ## Tech Talk Webinar Series ## Avalanche Rheometry for Metal Powder Flow Characterization This webinar has passed.
