Compressive properties and damping capacities of magnesium reinforced with continuous steel wire

The magnesium reinforced with continuous 304 stainless steel wire (304/Mg) was fabricated using an infiltration casting process. The 304/Mg has a novel internal structure. The compressive properties and damping properties of 304/Mg were tested. The stress-strain curve of 304/Mg was similar to that of metal rubber. The compressive strength and elastic modulus of 304/Mg were 42.8% and 55.6% higher than those of pure Mg, respectively. The energy absorption capability of 304/Mg was 2.5 times as high as that of pure Mg. Dynamic mechanical analysis (DMA) tests indicated that the damping capacity of pure Mg was higher than that of 304/Mg at low strain amplitude. Two internal friction peaks (P1 and P2) presented in the temperature-dependent damping curve. The P1 peak of 304/Mg shifted to lower temperature and P2 peak shifted to higher temperature compared to those of pure Mg. The preparation method of 304/Mg composite can be a reference to improve the damping capacity and strength of Mg.
