Abstract
A composite article comprising a metal and an amorphous metal bonded thereto by the explosion, being free from residual stress and compression stress in the amorphous metal portion, and having excellent magnetic properties inherent to the amorphous metal can be obtained by heating a composite article produced by bonding an amorphous metal to a metal through the explosion pressure to remove the residual stress caused in the amorphous metal during the explosion bonding, and then subjecting the heat treated composite article to a plastic working so as to give a tensile stress in the amorphous metal in an amount sufficient to offset the compression stress caused in the amorphous metal due to the heat treatment.
