ACQUISITION/DEVELOPMENT OF EQUIPMENT FOR MICROWAVE SINTERING IN-SITU CHARACTERIZATION Eugene Olevsky and Ronald Kline, San Diego State University, DMR-0315290 A unique experimental setup for microwave sintering online measurements has been developed. The computer-controlled Microwave Sintering System VIS-300-0a has been combined with a Confocal Fabry-Perot Interferometer and Yag Laser to enable the in-sintering ultrasonic measurements of the specific surface area evolution. In addition, the microwave system has been combined with an OFV Modular Laser Vibrometer to enable the in-sintering optical dilatometry. The developed experimental approach renders advanced processing control, which is important in the fabrication of functionally-graded powder composites. This combination of both dilatometry and in-situ ultrasonic evaluation opens extraordinary opportunities for full-fledged microwave sintering characterization.
ACQUISITION/DEVELOPMENT OF EQUIPMENT FOR MICROWAVE SINTERING IN-SITU CHARACTERIZATION Eugene Olevsky and Ronald Kline, San Diego State University, DMR-0315290 The project contributes to the development of the Joint Doctoral Program between San Diego State University and University of California,San Diego. The acquired equipment contributes to the research programs of multiple SDSU faculty members. The microwave sintering furnace enables sintering under protective atmospheres within temperature ranges, which are not available in using any other equipment of the SDSU College of Engineering. The microwave furnace has been already successfully employed for high-temperature sintering of ceramic functionally-graded composites. The project also included the participation of high-school students in the framework of the SDSU Upward Bound Program. The PI and the involved in the project graduate students mentored high-school students considering future college degrees in Mechanical Engineering.
