摘要：
The effect of alloy composition on limiting thickness for glass formation, and on glass transition, crystallisation and liquidus temperatures has been determined for the bulk glass forming Mg-Ni-Nd system, together with hardness, corrosion performance and wear resistance measurements. The results show that a large supercooled liquid range and a ratio of glass to liquidus temperature approaching a value of two-thirds are not, on their own, sufficiently sensitive to pinpoint optimum composition ranges for bulk glass formation in this system. These glasses showed higher hardness and higher corrosion resistance in 3.5% NaCl solution than reference, state-of-the-art and corrosion resistant magnesium alloys and their wear resistance is comparable. Their large supercooled liquid range (up to 48 K) allows easy deformation within this temperature interval, in contrast to microcrystalline material of the same composition.
