TMS Chapter Holds Topical Conference on Micrometallurgy The Conference was strucrured into five The Northern California Chapter of The topical sessions: (1) Physical MicrometalMetallurgical Society (TMS) sponsored a topical Conference entitled "Micrometallurgy: Characterization of Ultrafine lurgy '88: Nontraditional Metallurgy in a Structures, (2) Thermodynamics of Micrometallurgy: Prediction of StructureChanging Environment" March 10-11, Processing Relations, (3) Ultrafine Powder 1988 at Lake Tahoe, Nevada.

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
