6. Usage of Powder Technology
　　Extremely fine powder possesses a high reactiveness due to its increasing specific surface area. This feature can then lower both sintering time and temperature of such powder. Together with the concept of net-shape processing, this will lead to the development of new structural and functional parts fabricated from fine powder for the automotive, machinery, and electro-mechanical industries.
　　MEL has been conducting extensive research focusing on highly structured metal matrix composites, which having high specific strength and module based on aluminum and magnesium alloys.
　　China, Korea, Malaysia, Singapore and Thailand have participated in several collaborative research programs on aluminum composites. Australia is also taking part in a similar program on magnesium composites. Every step in the processing of powder such as atomization, compaction, consolidation, sintering, and deformation is thoroughly investigated. Recently, a gas atomizer, see the illustration, was set up at the Tsukuba Research Center No.2 to produce atomized magnesium alloy powder under an inert atmosphere. Conventional research on powder metallurgy and a newly developed sintering process are also being performed.
