Abstract:

 

To eliminate some problems in the production of composites by  classical methods, composite producing was performed by oxidising metallic   precursor, and mechanically alloyed Ba-Al powders were oxidised.  Mechanical  alloying proceses were applied with rolling and high-energy vibratory  ball mills and the effect of milling duration on the micro structure  was determined.  It was found that the powders were not  mixed completely and uniformly for even a 100 hour ball milling  duration.  It was also  found that a 5 hour high energy vibratory  milling time resulted in sufficient and uniform dispersion, and with  increasing milling time, mechanical alloying and uniform dispersion  were increased.
