Carbide Al4C3 intermediate product is firstly formed. The reaction is controlled by interdiffusion of elements. Further milling leads to transformation of Al4C3 to amorphous phase.Destabilization of Al4C3 is assumed to arise from the fact that defects and chemical disordering raise the free energy of crystal beyond that of the amorphous phase.
