“…In this study, it also can be seen that homogenized sample cannot maintain the damping capacity and drop drastically after achieved the peak just after 350°C temperature. The same trend of decreasing of damping capacity in as-rolled magnesium sheets also have been observed after achieved the peak at around 225°C [14].…”

“…In this study, the promising results in the increasing of damping capacity values at higher temperatures (above 350°C) has been achieved by homogenization at 560°C for 4 hours followed by 20 percent rolling reduction annealing at 345°C for 1 hour relatively. Previous study by Ning Ma et al have reported that the increase of damping capacity is attributed by the decreasing of annealing temperature [14]. However, in composite system combined with roll bonding, the results indicate that by increasing the percentage of reinforcing phase, the damping capacity increases.…”

Annealing treatment is an important step of rolling deformation that contributes to microstructural evolution and leads to the significant changes in damping capacity. Damping capacities were analyzed in the parallel to rolling direction at 1 and 10 Hz respectively. It was found that severe plastic deformation at 40 percent reduction has lower damping capacity compared to that of 30 percent and 20 percent reductions respectively. The microstructural results show that the grains of as rolled alloys were changed to almost equiaxed structures after a rolling reduction at 40 percent reduction.

“…In addition to spinel ferrites, the hexagonal ferrites—including M-type, W-type, X-type, Y-type, Z-type, and U-type—are also of great interest as high-frequency MAMs because of their planar magnetic anisotropy and natural resonance in the gigahertz range [90,91,92]. M-type barium ferrites (BaFe 12 O 19 ) and strontium ferrites (SrFe 12 O 19 ) are two typical examples of the hexagonal group that possess very strong uniaxial anisotropy, high saturation magnetization, and significant permeability [93,94], and thus the integration of BaFe 12 O 19 /SrFe 12 O 19 and CPs took a considerable share in the field of high-performance MAMs in the past decade [42,95,96,97,98,99,100,101,102]. However, high-temperature sintering (>800 °C) is always necessary for the formation of hexagonal ferrites [103], which results in serious agglomeration of ferrite particles and consequent difficulty in controlling the microstructure of the corresponding composites.…”

Microwave absorbing materials (MAMs) are paving the way for exciting applications in electromagnetic (EM) pollution precaution and national defense security, as they offer an advanced alternative to conventional reflection principles to fundamentally eliminate the EM waves. Conjugated polymer (CP)-based composites appear as a promising kind of MAM with the desirable features of low density and high performance. In this review, we introduce the theory of microwave absorption and summarize recent advances in the fabrication of CP-based MAMs, including rational design of the microstructure of pure conjugated polymers and tunable chemical integration with magnetic ferrites, magnetic metals, transition metal oxides, and carbon materials. The key point of enhancing microwave absorption in CP-based MAMs is to regulate their EM properties, improve matching of characteristic impedance, and create diversified loss mechanisms. The examples presented in this review will provide new insights into the design and preparation of CP-based composites that can satisfy the high demands of the oncoming generation of MAMs.

“…Thus, Mg-Dy alloys are susceptible to microstructural modifications by thermomechanical processes. It has been reported that microalloying with Dy has positive effects in both mechanical and corrosion properties [6,14,15], and the control of second phases precipitation is one of the critical steps during thermomechanical processing and heat treatments of these alloys.…”

In order to develop a potential route to fabricate plates and clips for orthopedic applications, a Mg–3.4Dy–0.2Zn–0.4Zr (wt.%) alloy was produced and analyzed in different conditions: solution treated at 525 °C for 3 h, hot rolled and hot rolled and aged at 250 °C. The aging behavior of the rolled alloy was investigated during isothermal aging at 250 °C, and a significant peak was observed at 10 h. The electrochemical behavior was evaluated in 0.9 wt.% NaCl solution at 37 ± 0.5 °C by potentiodynamic polarization and electrochemical impedance spectroscopy. The 525 °C-3 h and hot rolled specimens exhibited corrosion rates of 2.0 and 1.7 mm/year, respectively. The hot rolled and aged at 250 °C for 10 h specimen presented a grain size of 11.8 ± 1.7 μm with an intense macrotexture of the basal {0002} plane, hardness of 73 ± 3 HV and higher impedance modulus and obtained the highest corrosion resistance with a corrosion rate of 0.9 mm/year.
