“…Fe-based alloys with a porous structure can have a higher biodegradation rate due to the penetration of the body fluid into the porous structure. Microwave sintering is a new rapid sintering method that was successfully used to produce porous alloys in biomedical application [ 22 , 23 ]. Compared with conventional sintering, microwave sintering has higher microwave heating efficiency and more uniform heating, which can shorten the sintering time, enhance the diffusion of elements, and thus improve the mechanical properties [ 24 ].…”

This research produced a porous Fe-8 wt.% Cu alloy by microwave sintering in order to achieve (i) an increased biodegradation rate, and (ii) an antibacterial function. The Fe-8Cu alloy had higher density, hardness and degradation rate (about 2 times higher) but smaller and fewer surface pores, compared to the pure Fe. The Fe-8Cu alloy had a strong antibacterial function (the antibacterial rates against E. coli were up to 99.9%) and good biocompatibility. This work provides a novel approach of alloy design and processing to develop novel antibacterial Fe-based alloys.

“…The satellite peaks between Cu 2p 3/2 and Cu 2p 1/2 (941–945 eV) provide evidence of the existence of CuO [47]. The peaks observed at 232.6 eV and 235.8 eV (Figure 2e) can be attributed to the Mo 3d 5/2 and Mo 3d 3/2 , respectively, indicating that the valence of Mo in POMs is mainly VI [48]. The XPS spectra of Cu 2p and Mo 3d are in full compliance with the original skeleton of the POMs.…”

The ternary nanocomposites Fe3O4/Ag/polyoxometalates (Fe3O4/Ag/POMs) with core–shell–core nanostructure were synthesized by coating [Cu(C6H6N2O)2(H2O)]H2[Cu(C6H6N2O)2(P2Mo5O23)]·4H2O polyoxometalates on the surface of Fe3O4/Ag (core–shell) nanoparticles. The transmission electron microscopy/high resolution transmission electron microscopy (HR-TEM) and X-ray powder diffraction (XRD) analyses show that the Fe3O4/Ag/POMs ternary nanocomposites reveal a core–shell–core nanostructure, good dispersibility, and high crystallinity. The vibrating sample magnetometer (VSM) and physical property measurement system (PPMS) demonstrated the good magnetic properties and superparamagnetic behavior of the nanocomposites at 300 K. The UV–vis spectroscopy displayed the broadband absorption of the Fe3O4/Ag/POMs with the maximum surface plasmon resonance of Ag nanostructure around 420 nm. The dye removal capacity of Fe3O4/Ag/POMs was investigated using methylene blue (MB) as a probe. Through adsorption and photocatalysis, the nanocomposites could quickly remove MB with a removal efficiency of 98.7% under the irradiation of visible light at room temperature. The removal efficiency was still as high as 97.5% even after six runs by magnetic separation of photocatalytic adsorbents after processing, indicating the reusability and high stability of the nanocomposites. These Fe3O4/Ag/POMs photocatalytic adsorbents with magnetic properties will hopefully become a functional material for wastewater treatment in the future.

“…Usually, the conventional sintering process is carried out in a sintering furnace and may take up to several hours, which leads to excellent chemical homogenization, but also extensive grain growth. To protect material from this effect and reduce the sintering time, other techniques such as electric current-assisted sintering (ECAS), [8] spark plasma sintering (SPS), [9] microwave sintering [10] and induction sintering [11] were developed. Various thermally activated mechanisms are responsible for material transfer during sintering, causing a density increase.…”

The influence of the induction sintering process at different temperatures on the behavior of the powder metallurgy Ti-5Al-5Mo-5V-3Cr alloy was investigated. Material for the research was produced by elemental powder blending, followed by the uniaxial cold compacting process. Powder compacts were induction heated and sintered within the temperature range of 1000 °C to 1300 °C. The influences of process parameters on the material behavior during sintering and its properties were studied. The microstructure examination was performed with particular attention to the pore size and distribution as well as the homogenization of the microstructure. The sintering temperature of 1200 °C proved to be critical for the dissolution of most alloying powder particles. Hot compression tests were performed to determine the formability of the obtained material. Significant differences in flow stress behavior between samples sintered at temperatures below and above 1200 °C were observed. The mechanical properties of the material before and after deformation were compared. The evolution of the microstructure of sintered Ti-5Al-5Mo-5V-3Cr alloy after hot deformation was analyzed with an emphasis on its influence on the material properties. Based on the conducted research, it was found that the adequate homogenization of the chemical composition and microstructure was achieved at the temperature of 1250 °C, and a further increase did not reflect in a significant improvement.
