Abstract null null Corrosion process of Mg–Sn alloys is investigated via in situ synchrotron X-ray radiography, and corrosion rates are compared under potentiostatic and static immersion conditions. The occurrence and extension of corrosion pits are directly observed. The fine grains and higher volume of Mg2Sn in Mg–9Sn alloy reduce the anodic current density at -1.5 V potentiostatic polarization. However, the peeling of Mg2Sn phases off the alloy matrix increases the corrosion, and the corrosio...

Abstract null null Particulate-reinforced aluminum matrix composites are widely used owing to their advantageous comprehensive performance. For these composites, aging treatment is an important and essential process. However, researchers have discrepant opinions regarding the exact effects of particles on the aging behavior. In this study, the aging behavior of TiB2/2219Al composites is analyzed in terms of thermodynamics and kinetics. The results reveal that the particles can both promote aging...

Abstract The top-down method was used to fabricate the TiNi1+xSn half-Heusler alloy. Several knotty problems have been solved using the top-down method, including the generation of impurity phases, the visible discrepancy in the grain size of the TiNi2Sn second phase, and irregular variations in the Seebeck coefficient (S), electrical conductivity (σ), and thermal conductivity (κ) with increasing Ni content. The generation of a large number of incoherent interfaces between the half-Heusler (HH) ...

Abstract The microstructure, bio-corrosion properties and cytotoxicity of as-extruded Mg–5Sn–xIn (x=0, 1, 2, 3, 4, all in wt%) alloys were investigated in vitro for biomedical applications. The results show that the microstructure of all alloys exhibits a partially recrystallized structure, and the area fraction of dynamically recrystallized (DRXed) grains increases with In addition. Mg2Sn particles are mostly precipitated at DRXed grains. Weight loss and potentiodynamic polarization measurement...

Abstract null null The microstructural observation, the mass loss test, potentiodynamic polarization measurements and corrosion morphology examinations were conducted to study the influence of microstructural characteristics on corrosion behavior of Mg–5Sn–3In alloys in Hank's solution after extrusion. The results show that the corrosion rate of the as-cast alloy is similar to that of as-extruded alloy; however, the local corrosion susceptibility is greatly weakened in the as-extruded alloy, esp...

Abstract Flexible thermoelectric materials are presented with potential applications in electronic devices and energy conversion due to their convenient preparation, good flexibility, and various forms. However, as ductility is rarely observed in inorganic semiconductors and ceramic insulators, reports on applications of inorganic oxide materials in flexible thermoelectric materials are sparse. Here, we report a new method for the synthesis of a flexible Na1.4Co2O4 thermoelectric material based ...

Abstract The effect of Ga element on microstructure, corrosion behavior and tensile mechanical properties of as-extruded Mg–5Sn–xGa (x=0, 1, 2, 3, all in wt%) alloys was investigated using immersion test, electrochemical test and tensile test. The results show that the Mg2Sn and Mg5Ga2 particles are dynamically precipitated during extrusion process, and the volume fraction of Mg5Ga2 precipitates increases with increasing Ga content. The corrosion resistance of Mg–5Sn alloy in the immersion test ...

Abstract In this work, Cu–Cr–Zr–ZrB2 composites were prepared via in situ melt reaction, casting and aging treatment. The reinforcement involved both micro ZrB2 particulate, primary Cr particles and nano precipitates, formed by in-situ reactions in copper melt and specific aging, respectively. The effect of the two reinforcements on the mechanical properties, thermal stability and tribological behavior of the Cu–Cr–Zr–ZrB2 composites were investigated. The ultimate tensile strength, electrical c...

Abstract Cu-Ni-Mn based alloys have long been considered as potential thermoelectric materials because of their Seebeck effect and large power factor. In this study, bulk Cu-Ni-Mn based alloys with nanostructures were prepared via melting and cryorolling, and their thermoelectric and mechanical properties were analyzed. A large number of nanotwins and nanoprecipitates were observed in the prepared alloys using transmission electron microscopy. These observations indicate that the bulk Cu-Ni-Mn a...
