For what I understand, the "liquid" part in various trade names given to amorphous alloys references their amorphic structure, unusual for metals (typically quite regular crystals), but common in liquids -- even apparently "solid", as glass. They have some interesting (for metals) properties, for one -- excellent thermoplasticity at relatively low temperatures, with no hard melting point (just like glass compared to steel -- there is a reason one can blow glass, but steel has to be mauled).
