FeCoNiCrCu high-entropy alloy (HEA) and Cu foils were utilized as the intermediate layer to conduct laser welding of TC4 titanium Q345 steel. Welding is performed by adding single HEA Cu/HEA double interlayer respectively. We conducted in-depth studies on microstructure mechanical properties joint stereomicroscopy, metallographic microscope, scanning electron microscope (SEM), micro-area X-ray diffraction (XRD), nanoindentation, backscatter (EBSD), tensile testing. The results indicate that...
Resistance switching (RS) devices that are based on titanium dioxide (TiO2) nanomaterials have recently attracted substantial research interest because of their simple preparation technology and potential applications in the memory devices. In this paper, RS characteristics TiO2-based memristors were regulated by changing crystal structure TiO2 film. Resistive memory, consisting Ag/amorphous TiO2/Ti fabricated anodic oxidation, exhibited poor cycling stability. Annealing was applied to...
Zr-4 alloys were vacuum brazed using Ag–Cu–Ti filler metal. The effect of brazing temperature on the microstructure evolution, shear strength and corresponding fracture behavior joints was investigated. typical phases at 800, 840 930 ∘ C inferred to be three different microstructures, i.e., a mixture (Cu, Ti) Ag-rich phase, phase brittle intermetallic compound (IMC) AgZr, uniformly mixed morphology CuZr AgZr. And width whole seam increased from 78.4[Formula: see text][Formula: text]m...
Titanium dioxide is one of the earliest materials used in memristors. It widely studied and researched due to its advantages simple preparation process, high dielectric constant, wide bandgap chemical stability. In this paper, a two-step anodization process was prepare oxidized nanotubes array, which served as foundation for fabricating Ag/TiO 2 /Ti The research delved into impact diverse oxidation voltages on resistive performance memristor discussed underlying mechanism resultant performance.
Combining Mg and Al dissimilar metals further reduces structural weight, but the formation of intermetallic compounds (IMCs) affects Al/Mg joint properties. To prevent IMCs, a Ni-Al2O3 composite coating was pre-plated on alloy substrate, then Sn3.0Ag0.5Cu (SAC 305) solder utilized to facilitate joining AZ31 Mg/6061 through ultrasonic-assisted soldering. We investigated impact Al2O3 nano sol content in microstructure evolution, IMCs formation, mechanical Results indicated that effectively...
