ASTM COMMITTEE B09 WORKSHOP ON POWDER CHARACTERIZATION
New powder characterisation tests such as the rotating drum and the Freeman FT4 rheometer have been introduced in recent years. These instruments have yet to be standardized for use with metal powders. Greg Martiska, Mercury Scientific Inc., presented the results of testing with the Revolution Powder Analyser and Joe Tauber, Kennametal Inc., presented data from testing with a Granudrum. The third workshop participant was Tim Freeman, Freeman Technology, a Micromeritics company. He presented the test results obtained using the FT4 rheometer.
