Ultra magnesium-rich, low-density Mg–Ni–Ca bulk metallic glasses

A range of low-density Mg-rich glass-forming compositions from the Mg–Ni–Ca alloy system have been discovered. Distinct maxima in the glass-forming ability were located and shown to produce samples of bulk metallic glass dimensions. These bulk glass-forming alloys exhibit the lowest density ( −3 ) and highest Mg content (86 at.%) of all Mg-based bulk metallic glasses reported to date. Here, the specific alloy design method and a range properties of these amorphous alloys are revealed.
