铝基非晶态金属是一种有趣的轻质合金，具有上级机械和腐蚀性能，但从未以块体形式获得。在这里，我们报告的第一次成功获得富铝（86原子%），Al）块体金属玻璃（BMG），基于从优选的内部玻璃结构设计的合金组成。所发现的铝基非晶合金不仅表现出明显的塑性，而且还表现出比强度。
Aluminum-based amorphous metals are interesting lightweight alloys with superior mechanical and corrosion properties, but have never been achieved in bulk form. Here we report the first success of obtaining Al-rich (86 at.% Al) bulk metallic glasses (BMGs), based on an alloy composition designed from the preferable internal glass structure. The Al BMGs discovered exhibit ultrahigh specific strength, as well as obvious plasticity.
