Abstract

An amorphous metal foam with a bulk density of 3.4g/cm ³ was developed by low-pressure melt infiltration of the bulk metallic glass-forming alloy Zr ₅₇Nb ₅Cu _15.4Ni _12.6Al ₁₀ into a bed of hollow carbon microspheres, followed by rapid quenching. The foam consists of a glassy metallic matrix containing ∼60 vol.% of homogenously distributed carbon microspheres, 25-50 μm in diameter, with small amounts of ZrC at the interface. It was observed that an amorphous foam with 5 mm diameter showed no measurable loss in thermal stability as compared to the amorphous alloy in bulk form.
