Abstract Nanolattices exhibit attractive mechanical properties such as high strength, specific and energy absorption. However, at present, materials cannot achieve effective fusion of the above scalable production, which hinders their applications in conversion other fields. Herein, we report gold copper quasi-body centered cubic (quasi-BCC) nanolattices with diameter nanobeams small 34 nm. We show that compressive yield strengths quasi-BCC even exceed those bulk counterparts, despite...
