将块体金属玻璃形成合金Zr57Nb5Cu15.4Ni12.6Al10低压熔体浸渗到中空碳微球中，然后快速冷却，得到了体积密度为3.4g/cm(3)的非晶态金属泡沫。泡沫由一种玻璃状金属基质组成，其体积分数约为60。%的均匀分布的碳微球，直径为25-50微米，在界面上有少量的ZRC。与块状非晶态合金相比，直径为5 mm的非晶态泡沫在热稳定性方面没有明显的损失。(C)2004年美国物理研究所。
An amorphous metal foam with a bulk density of 3.4 g/cm(3) is created by low-pressure melt infiltration of the bulk metallic glass-forming alloy Zr57Nb5Cu15.4Ni12.6Al10 into a bed of hollow carbon microspheres, followed by rapid quenching. The foam consists of a glassy metallic matrix containing similar to60 vol. % of homogenously distributed carbon microspheres, 25-50 mum in diameter, with small amounts of ZrC at the interface. An amorphous foam with 5 mm diameter showed no measurable loss in thermal stability as compared to the amorphous alloy in bulk form. (C) 2004 American Institute of Physics.
