    Abstract:

    The electrical resistivities of the amorphous matrix and the nanocrystaline phase in the Al-Y-Ni-Co alloys were separated. Calculations show that the decrease of total resistivity during crystallization is related to the structural changes of amorphous matrix. The observed electrical resistivity suppression in the amorphous matrix is consistent with the Ziman model. The temperature dependence of the nanocrystalline fraction was evaluated and discussed.
