Abstract

Glass-formation and devitrification of the glassy phase in the Ni-Nb-Zr-Ti and Ni-Nb-Zr-Ti-NM (NM, noble metals) system alloys exhibiting the supercooled liquid on heating were investigated. The crystallized structure and kinetics of devitrification of Ni-Nb-Zr-Ti-Pd glassy alloy are studied in detail. The formation of the glassy single phase has been proven using high-resolution transmission electron microscopy (TEM). The addition of Zr and Pd increases the supercooled liquid region of the Ni₆₀Nb₂₅Ti₁₅ (numbers indicate at.%) alloy from 44 K to about 50 K. The cP2 TiNi phase was found to form during the first exothermic phase transformation in all studied alloys. The addition of Zr to Ni-Nb-Ti alloy prevents formation of oP8 Ni₃Nb phase observed in the Ni₆₀Nb₂₅Ti₁₅ alloy and initiates formation of the primary Ni₁₀Zr₇ phase while the additions of both NM and Zr effectively refine cP2 TiNi particles size. Definite fractions of rhombohedral R and hR14 Ni₄Ti₃ phases were also observed in NM-bearing alloys. Significantly lower growth rates of the devitrification products in the NM-bearing alloys compared to the Ni-Nb-Ti one may be the reason for the improvement of glass-forming ability (GFA).
