Al-rich bulk metallic glasses with plasticity and ultrahigh specific strength B.J. Yang, J.H. Yao, J. Zhang, H.W. Yang, J.Q. Wang* Shenyang National Laboratory for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, 72 Wenhua Road, Shenyang, 110016, China E. Ma* Department of Materials Science and Engineering, Johns Hopkins University, Baltimore, MD 21218, USA 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 * Corresponding authors E-mail: jqwang@imr.ac.cn (J.Q. Wang), ema@jhu.edu (E.
