“…The addition of the Zr element has diverse effects on magnesium alloys. Grain refinement has been proven to be an important method for simultaneously improving the strength and ductility of metals and alloys [ 55 , 56 ]. The addition of the Zr element can greatly refine the grain size of magnesium alloys and improve their resistance to heat.…”

As the lightest structural metal material, magnesium alloys possess good casting properties, high electrical and thermal conductivity, high electromagnetic shielding, and excellent damping properties. With the increasing demand for lightweight, high-strength, and high-damping structural materials in aviation, automobiles, rail transit, and other industries with serious vibration and noise, damping magnesium alloy materials are becoming one of the important development directions of magnesium alloys. A comprehensive review of the progress in this field is conducive to the development of damping magnesium alloys. This review not only looks back on the traditional damping magnesium alloys represented by Mg-Zr alloys, Mg-Cu-Mn alloys, etc. but also introduces the new damping magnesium materials, such as magnesium matrix composites and porous magnesium. But up to now, there have still been some problems in the research of damping magnesium materials. The effect of spiral dislocation on damping is still unknown and needs to be studied; the contradiction between damping performance and mechanical properties still lacks a good balance method. In the future, the introduction of more diversified damping regulating methods, such as adding other elements and reinforcements, optimizing the manufacturing method of damping magnesium alloy, etc., to solve these issues, will be the development trend of damping magnesium materials.

In this paper, a low-cost and high-performance Mg–4Y–3Nd–1.5Al rolled magnesium rare earth alloy sheet was developed by a multi-pass rolling process. The effect of cumulative rolling deformation on the microstructure and mechanical properties of the alloy sheet was studied. It is found that with the increase of rolling passes, the proportion of dynamic recrystallisation grains increases, the grains are refined and the texture strength is weakened due to the combined effect of particle excitation nucleation mechanism and grain-boundary-induced nucleation mechanism. The results show that fine-grain strengthening and work hardening are the main reasons for the high strength of the alloy sheet. This experiment provides scientific guidance for developing fine-grained magnesium alloy sheets.
