Original abstract
Mechano-chemical processing route appears to be an advanced technique for synthesis of nano – sized materials of composite type. The work is focused on the synthesis of Nb-Nb3Al/Al2O3 composite by mechanical alloying (MA). For these purposes, a mixture of niobium (V) oxide and pure aluminium powders was subjected to high energy ball milling. The structural and phase analyses of powder particles before and after milling for different times was conducted by scanning electron microscopy (SEM) and X – ray diffractometry (XRD). Thermal properties were detected by using differential scanning calorimetry (DSC). Formation of the Nb/Nb3Al nanocomposite was proved, as a side effect of the reactions almost alumina matrix was formed during mechano-chemical reaction for the Nb2O5 / Al ratio used.
