Non-Agglomerated Nanodiamonds Inside Metal Matrix

This work is concerned with the study of some aspects related to nanodiamond de-agglomeration in metal matrix composites during mechanical alloying, as well as to the study of impact of non-agglomerated state of nanodiamonds in aluminum matrix on the material properties. It is demonstrated that phase transformations in matrix during mechanical alloying stimulate the nanodiamond de-agglomeration. It is demonstrated as well that non-agglomerated nanodiamonds with the size approximately of 5 nm start to react with the aluminum matrix under the temperatures of 470-550 degrees C, which is significantly lower compared to the reaction start temperature for macro-objects (it's lower approximately by 500-700 degrees).
