Aluminum-based amorphous metals are interesting light-weight alloys with superior mechanical and corrosion properties, but have never been achieved in the 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 ultra-high specific strength, as well as obvious plasticity.
Key Words: Aluminum alloys, metallic glasses, specific strength, plastic deformation
