The tensile fracture structure in the as-quenched Zr80Pt 20 alloy hardened by the homogeneously precipitation of nanoicosahedral phase is investigated by high-resolution transmission electron microscopic observation. The evidence which indicates that the tensile fracture occurs in the residual amorphous phase in the intergranular region, is obtained in the nanocomposite alloy consisting of icosahedral and amorphous phases.
