摘要：

Based on X - ray diffraction investigations, scanning electron microscopy observations and chemical energy dispersive analyses, the nanocrystalline and amorphous phase formation in the Ni Al Al - M (M = Fe, Zr) has been investigated. The effects of the injected mechanical power and of the ethanol solvent addition on the stationary end - product have been studied. The effect of embrittling/ductilizing element on the crystal to amorphous phase transition has been investigated supporting the idea of a critical grain - refinement induced phase transition.
