| Abstract: | The foamed magnesium material is a kind of new materials with huge potential, and it has many special properties compared to the solid metal magnesium material and the foamed aluminum material. However, the domestic research on the foamed magnesium material is relatively small. For the convenience of scholars of the foamed magnesium material, this paper briefly introduces several kinds of performance features of the foamed magnesium material, discusses process principles, advantages and disadvantages of several important foamed magnesium material preparation methods such as the seepage flow casting method, the investment casting method, the powder metallurgy method, the melt foaming method and the metal-gas eutectic directional solidification method, and lists some examples of foamed magnesium material preparation at home and abroad. The application prospects of the foamed magnesium material in the fields of aerospace, biomedicine, radiators and automobiles are analyzed based on its damping, energy absorption, bionic and heat dissipation properties. |
