1986 TMS ANNUAL MEETING March 2-6, 1986 New Orleans Marriott Hotel New Orleans, Louisiana

T h e 115th Annual Meeting of The Metallurgical Society continues the tradition of technical excellence and leadership in the metallurgical and materials sciences. A comprehensive program featuring more than 900 papers in 146 sessions will provide the latest industry developments in this world renowned technical forum.

26 Light Metals sessions will highlight the EXTRACTIVE METALLURGY program, commemoratintf the 100th anniversary of the Hall- Heroult ~rocessfor aluminum production. Other topics to be addressed include Plasmas for Metallurgical Applications: Hydrometallurgical Reactor Design and Kinetics. This year's PHYSICAL METALLURGY Sessions include the Hume Rothery Symposium on Undercooled Alloy Phases: Experimental Methods and Techniques for Microgravity Materials Science Research and High Temperature Science: and the Earl R. Parker Symposium covering StructureIProperty Relationships. Other MATERIALS SCIENCE programming includes sessions on Sensors: Devices, Materials and Processing: Electrical Properties of Organic Materials: and Electronic and Magnetic Materials among other presentations.

Roundtable luncheons and numerous special events offer an excellent opportunity for informal professional exchange. New Orleans, known for its jazz and unique French Quarter, is an outstanding attraction for dining and entertainment.
