Abstract

Metal parts fabricated by pressed and sintered powders are stronger, more durable and more easily fashioned into complex shapes than similar materials cut from preformed metal. These advantages along with the elimination of most of the waste from machining metal parts make powdered metal fabrication very economically attractive. This talk will describe preliminary efforts to utilize an alternative source of iron oxide derived from treatment of AMD as input feed stock into this process. The initial characterization of the fabricated parts suggest the use of chemically precipitated nano-particles of iron oxyhydroxide and gypsum form what can be described as a particle strengthened metal matrix composite material with chemical, mechanical, and performance properties that, when optimized, could offer a significant economic alternative material in the market place.

Biography

Barry E. Scheetz, Professor of Materials, Civil and Nuclear Engineering, has been a faculty member at the Pennsylvania State University for 30 years. During this time, Professor Scheetz has focused his research on a variety of environmental issues concerning nuclear waste disposal and the utilization/reutilization of industrial waste materials, so-call "cast-off materials". A significant portion of his research activities has centered on mineland reclamation. Recent programs have been utilizing fly ash and alkaline waste activators to fabricate non-traditional alkali-activated cements for large volume use in environmental restoration. Professor Scheetz holds approximately 40 combined U.S. and foreign patents and is the author of 200 scientific publications. He has served on numerous National Research Council committees.
