Mechanical behaviour and microstructure evolution of wrought magnesium alloys under dynamic compression loading: a review

As one of the lightest structural metals, magnesium alloys have attracted enormous attention owing to its attributes of high specific strength and specific stiffness, superior damping capacity and shock absorbency and so on. The wide application fields of wrought magnesium alloys include aerospace, transportation, and so on. It is critical to understand the correlation between dynamic mechanical response and microstructure evolution of wrought magnesium alloys in stringent impact service environment. Split Hopkinson pressure bar has become the universal and common apparatus to investigate the dynamic compression mechanical behaviour of materials under impact loading state. The recent development of dynamic (high strain rate) compression mechanical behaviour and microstructure evolution of common wrought magnesium alloys are summarized in this paper. The research directions in the future are also suggested.
