Summary: This study investigates the micro-cutting of additively manufactured high-strength maraging steel and its relationship with microstructural features, mechanical properties, and the effectiveness of the mechanochemical effect. The results show that the mechanochemical effect can be induced successfully, leading to substantial reductions in cutting forces and improvements in surface quality. However, the presence of nanoparticles in age-treated steel renders the mechanochemical effect ineffective in improving machinability.

Summary: In this study, spherical amorphous boron particles with an average size of 380 nm were successfully prepared using a novel silicothermic reduction method. The low-viscosity melt in the reaction system facilitated the reduction and absorption of silica, a water-insoluble by-product. The improved silicothermic reduction produced alkali silicate as a by-product, which could be easily separated and serves as an important recyclable industrial material.

Summary: Investigating the effects of adding Ti3AlC2 and sintering temperature on the microstructure of Cu-graphite composites, it was found that Ti3AlC2 and Cu undergo interdiffusion during sintering. A certain amount of Ti3AlC2 is in situ decomposed to synthesize TiCx due to the diffusion of Al atoms into the Cu matrix. The decomposition of Ti3AlC2 is directly proportional to the sintering temperature but inversely proportional to its addition. Furthermore, a TiC interface layer is formed, promoting good bonding between the Cu matrix and graphite, through the reaction of Ti atoms decomposed from Ti3AlC2 and carbon atoms on the graphite surface.

Summary: Copper-graphite-Ti2SnC composites were prepared by argon sintering using copper-coated graphite, copper and Ti2SnC as raw materials. The phase composition and microstructure of the composites were investigated at different content and sintering temperatures. The results showed that Ti2SnC decomposed into TiCx during sintering, and inter-diffusion occurred between Cu atoms and Sn atoms. The degree of Ti2SnC decomposition was influenced by the sintering temperature and the ratio of Cu to Ti2SnC content.

Summary: Gas-atomized (GA) and water-atomized (WA) commercially pure iron (cp-Fe) powders were processed using laser-based powder bed fusion, resulting in slightly higher porosity for the WA condition. Fatigue tests, which are negatively affected by porosity, also showed good properties for the WA condition. The microstructure stability significantly differed between the GA and WA specimens and can be explained based on chemical composition. The GA specimens exhibited yield phenomenon and softening under cyclic loading, while the WA specimens maintained microstructure stability in cyclic tests.

Summary: Magnetic Fe3O4@TiO2 nanospheres supported by mesoporous silica aerogel substrate were synthesized using a simple combining procedure of sol-gel and ultrasound assisted reflux technique for photocatalytic activity. The resulting ternary nanocomposite showed highly dispersed and covered Fe3O4@TiO2 nanoparticles on the silica aerogel. The prepared hydrophobic porous silica aerogel exhibited fine particulate morphology with low density and good degree of porosity. The Fe3O4@TiO2 on the silica aerogel nanoparticles formed a core shell spherical morphology with decreased BET surface area, confirming the formation of Fe3O4@TiO2/silica aerogel nanocomposite. The prepared ternary nanocomposite demonstrated good photocatalytic activity for the removal of tetracycline from water under visible light.
