It is found that an increase in the hydrostatic chamber pressure (P) during the casting process suppresses the glass forming ability (GFA) of the Zr65Al7.5Ni10Cu17.5 alloy, on the contrary, it enhances the GFA of the Zr65Al7.5Ni10Pd17.5 alloy. This opposite dependence of the GFA on P in these alloys may be because the volume increases or decreases by the primary crystallization. [Copyright &y& Elsevier]

To increase the surface area while decreasing the ligament size of an Nb anode pellet for use as a capacitor, we added Ce to an Mg melt; the dealloying reaction occurred at temperatures lower than 1023 K, the previously lowest recorded temperature for such a reaction. By analyzing the dealloying kinetics, we found the optimum dealloying conditions to produce a minimum ligament size of 100 nm in the Mg 95.7 Ce 4.3 melt: 923 K for 420 s. Using these conditions, we increased the specific surface area of the Nb anode pellet to 4.3 m 2 /g, which increased its mass-specific capacitance to 875,000 μFV/g. [ABSTRACT FROM AUTHOR]
