The tfurd session, Powder Processing and Production Techniques, began with several inyited papers on the new area of nanocrystalline materials. The papers emphasized transport phenomena in these materials, from the perspective of both fundamental measurements and also sintering rates in these materials. The remaining papers described recent work on the production of metallic powders for pow
