We have investigated the effect of additional elements, mainly Ni, on the properties of the Mg90Pd10 amorphous alloy, which has the significant sensitivity to hydrogen dissolved in water. The results have shown that the Ni addition to the Mg90Pd10 amorphous alloy brings about complicated changes in the thermal stability, the electric property and the sensitivity to hydrogen dissolved in water. The sensitivity of the (Mg0.9Pd0.1)100-xNix amorphous alloy has a tendency to decrease with increasing the Ni content. Nevertheless, the Ni addition is more preferable as for the thermal stability of the amorphous phase and the sensitivity to hydrogen than the Cu, Al, Ti or Co addition.
