Beryllium–aluminum alloy is expected to become a key material for the lightweight of China’s new generation of aerospace equipment due to its excellent properties such as light weight

high specific stiffness and high specific strength. However

beryllium and aluminum have low solid solubility at room temperature and do not form intermetallic compound

resulting in poor interface bonding

which become the key to restrict improvement of the strength and plasticity of beryllium–aluminum alloy. In this paper

research status of the interface structure regulation of beryllium–aluminum alloys is reviewed

including the structural characteristics of the beryllium–aluminum interface

morphology of the beryllium phase

regulation of BeO

and alloying of the matrix. This paper focuses on the research progress of matrix alloying composition design to regulate the beryllium–aluminum interface structure

expecting to provide reference for the research on material composition design optimization and performance improvement of beryllium–aluminum alloys and other similar systems.
