    This review describes a four-dimensional (4D) impedance analysis approach for analyzing the oxide film formation process that accompanies the dissolution of metals and alloys. In this analysis, the measured impedance was plotted on a three-dimensional (3D) complex impedance plot composed of real, imaginary, and time axes. Since the impedance plots of the same frequency in each spectrum are smoothly connected using a spline under tension function, the instantaneous impedance can be determined at an arbitrary time on the 3D complex impedance plot. In this review, the application of 4D impedance analysis to an additively manufactured aluminum alloy produced by a laser powder bed fusion process is introduced as a representative additive manufacturing technology. Additionally, the corrosion resistance mechanisms are discussed based on the impedance variation, which is attributed to dissolution and oxide film formation to generate a unique alloy structure.

    Al–2.5 mass% Fe binary alloys were prepared by laser powder bed fusion (L-PBF), and the effects of annealing below 573 K on the electrical, mechanical, thermal properties, microstructure, and residual stress were investigated. The electrical resistivity of the L-PBF alloy remained almost unchanged after annealing at 473 K, while that of the specimen annealed at 573 K decreased from 20 to 8 nΩ m and from 47 to 37 nΩ m at 77 K and 293 K, respectively. Vickers hardness (measured on the surface normal to the building direction) increased to about 102 HV from 97 HV, then decreased to 94 HV during annealing at 573 K, showing a similar trend on the parallel surface. These hardness changes agreed with the formation of nanoscale Al<inf>6</inf>Fe precipitates, corresponding to a decrease in solute Fe concentration of about 0.47–0.52 mass% estimated from electrical resistivity and X-ray diffraction. Compression tests revealed no anisotropy in the 0.2 % proof stress between as-built and annealed specimens. Residual stress was effectively removed by annealing at 573 K for >120 s. Annealing also increased the specific heat from 800 to 920 J/(kg·K), attributed to reduced solute Fe and an increased Al<inf>6</inf>Fe fraction. The measured thermal conductivities agreed well with reported values.

    Nanoparticles of Ce-based intermetallic heavy-fermion superconductor CeCoIn<inf>5</inf> with roughly 500 nm diameter were fabricated via pulsed laser ablation in pure water using Nd:YAG laser. Despite the surface oxidization and chemical inhomogeneity of the grown products, microstructural analysis confirms the presence of stoichiometric CeCoIn<inf>5</inf> nanoparticles, demonstrating that they are ready to be tested as a possible candidate for thermally stable and corrosion-resistant materials.

    The influence of hydrogen on the dynamic precipitation and morphology of Si particles in additively manufactured Al-12Si alloys was experimentally and numerically investigated. For the first time, hydrogen was observed to transform Si precipitates from globular to plate-like morphologies, with an increase in yield strength when the hydrogen content exceeds a critical value. Computational analysis indicated that the interface of Si particles could act as potential hydrogen traps, as suggested by density functional theory (DFT) calculations. Thermodynamic insights revealed that hydrogen likely increases interfacial entropy, stabilizes coherent interfaces, and reduces interfacial energy. These findings are consistent with the HEENT mechanism, which explains how hydrogen-enhanced entropy contributes to microstructural changes and alters the mechanical properties of metals. These findings suggest that hydrogen can influence precipitate morphology through its combined effects on thermodynamic stability and kinetic processes, offering new insights into the behavior of additively manufactured aluminum alloys under hydrogen exposure.

  5. Role of Si Addition in Interfacial Reactions of Steel Sheets Hot-dipped in Zn–55%Al Alloy Melt Open Access

    <p>This study was set to fundamentally understand the effect of Si addition on the interfacial reaction between Zn–55%Al alloy liquid (corresponding to a nominal composition of Al–25Zn (at%)) and Fe solid in the production process of GALVALUME steel sheets. The pure Fe sheets were hot-dipped in Al–25Zn and Al–25Zn–2Si (at%) alloy melts at 600, 650, and 700°C for 2~3600 s. Significantly thick coatings were formed on Fe sheets hot-dipped in the Al–25Zn binary alloy melt for a longer time than 10 s. The coating thickness became several millimeters after 30 s, resulting in a delamination of the coating. The significant Fe dissolution occurred in the Al–Zn binary alloy melt, accompanied by a significant growth of η phase (Fe<sub>2</sub>Al<sub>5</sub>) toward the solid Fe. The growth could be promoted by the Zn-rich liquid phase with a lower melting temperature. However, in the case of hot-dipping in the Al–25Zn–2Si ternary alloy melt, uniform coatings were formed on the hot-dipped Fe sheets due to the suppressed interfacial reactions. The Fe dissolution slightly occurred, and a continuous layer of Si-rich T<sub>5</sub> (Fe<sub>2</sub>Al<sub>7.4</sub>Si) phase was formed at the interface of solid Fe with the Al–25Zn–2Si alloy melt. The continuous T<sub>5</sub> phase layer would play a role in a diffusion barrier at the interface of solid Fe with liquid Al–Zn alloy, resulting in the suppressed interfacial reaction. These interfacial reaction processes are discussed based on thermodynamic calculations of the Fe–Al–Zn ternary and Fe–Al–Zn–Si quaternary systems.</p>

  6. Anomalous temperature-dependent strength of copper alloy manufactured by laser-beam powder bed fusion Open Access

    This study reports an anomalous temperature-dependent tensile behavior of laser-beam powder bed fusion (PBF-LB) processed Cu–Cr–Zr alloy. The yield strength of the alloy initially decreases as the temperature increases to 200±5 MPa and then increases to 350±11 MPa at 500°C before reducing to 234±6 MPa at 600°C. The microstructure consists of elongated Cu grains with a high concentration of Cr solute (∼1 mass%), resulting from rapid solidification during the PBF-LB process. Transmission electron microscopy for the specimens deformed at 500°C revealed the presence of numerous nanoscale Cr-rich particles embedded inside the supersaturated solid solution of the Cu matrix. Nanoscale particles can act as barriers to dislocation motion, leading to an increase in internal stress during plastic deformation at elevated temperatures. This work provides the high potential of post heat treatments for achieving superior mechanical performance using high solute supersaturation formed by the PBF-LB process.

    Four-dimensional (4D) electrochemical impedance spectroscopy was applied to clarify the role of microstructures on the corrosion behaviour of Al-Si alloys additively manufactured by laser powder bed fusion in the immersion of NaCl solution. 3D complex impedance plots, comprising real, imaginary, and time axes, indicate that the impedance increases gradually at initial stage and then does not show apparent time variation. These behaviours, following surface morphology analysis, are strongly related to the remaining fine silicon particles on the surface due to the preferential Al dissolution, which suppress the further dissolution from underlying along with the protective oxide film formation.

    High-entropy alloys (HEAs) are a class of materials known for their unique properties, including high strength, excellent wear resistance, and good corrosion resistance. Sub-micron- and nanosized HEA particles were fabricated via pulsed laser ablation in liquid using a Cantor alloy target. The Cr<inf>20</inf>Mn<inf>20</inf>Fe<inf>20</inf>Co<inf>20</inf>Ni<inf>20</inf> target was immersed in pure water and ablated using a focused nanosecond-pulsed Nd: YAG laser. A dark solution containing HEA particles was obtained which was stable for about one week before agglomeration and precipitation was observed. The diameters of the obtained particles ranged from several tens of nanometers to several hundred nanometers. Increasing the laser power resulted in higher particle concentration and an increase in the intensity of UV-vis absorption spectra. Electron diffraction was used to confirm that the composition of the particles was close to that of the Cantor alloy, although the concentrations of Cr and Mn were slightly deficient. There was also a weak dependence of the composition on laser power, and all the particles also contained oxygen. Selected area electron diffraction revealed that the composition varied spatially within some particles and that they are mainly polycrystalline. This work shows that HEA particles can be quickly, safely, and effectively manufactured using liquid-based laser ablation, opening the pathway for mass manufacture and disruptive applications in, e.g., catalysis or tribology.

    This study identifies the role of solute Cr in the thermal activation process in the plastic deformation of α-(Fe, Cr) ferrite (BCC solid solutions) using micropillar compression tests for micron-sized single-crystals fabricated on various Fe–Cr binary alloys that were solution-treated at 1573 K. Fe–18%Cr single-crystal micropillars with a mean diameter d of ∼2 μm exhibited a relatively higher strain rate sensitivity (m) of 0.12 for the stress required for slip initiation. Larger Fe–18%Cr micropillars (d = 5 μm) exhibited a lower m value of 0.04. The corresponding activation volume of 50 b<sup>3</sup> was equivalent to the millimeter-sized pure Fe and Fe–18%Cr alloy specimens (60–70 b<sup>3</sup>), indicating the prevalence of a general mechanism involving dislocation motion (kink-pair nucleation of screw dislocations). This mechanism controls the thermal activation process of plastic deformation in the Fe–18%Cr alloy, which has sufficient sources for dislocation multiplication. In the Fe–25%Cr and Fe–40%Cr single crystal micropillars, a less pronounced size-dependent m value (0.01–0.03) was determined, almost independent of specimen size. The corresponding activation volumes of large micropillars (74–77 b<sup>3</sup>) were similar to those of millimeter-sized specimens, which indicates a mild effect of solute Cr atoms on the thermal activation process of dislocation motion in Fe–Cr binary alloys at ambient temperature. Initial dislocations, rather than Cr content in Fe–Cr binary alloys, led to the low changes in size-dependent activation volume of Fe–Cr alloys with higher Cr content. Planar faults (Cr-enriched regions) were observed in Fe–40%Cr alloys, which may become sufficient sources for dislocation nucleation. However, the influence of Cr-enriched regions on dislocation motion remains unclear.

    An attempt was made to apply digital image correlation (DIC) strain analysis to in-situ scanning electron microscopy (SEM) observations of bending deformation to quantify local strain distribution inside a ZnMgAl-alloy coating in deformation. Interstitial-free steel sheets were hot-dipped in a Zn-3Mg-6Al (mass%) alloy melt at 400 <sup>o</sup>C for 2 s. The specimens were deformed using a miniature-sized 4-point bending test machine inside the SEM chamber. The observed in situ SEM images were used for DIC strain analysis. The hot-dip ZnMgAl-alloy coating exhibited a solidification microstructure composed of a three-phase eutectic of fine Al (fcc), Zn (hcp), and Zn<inf>2</inf>Mg phases surrounding the primary solidified Al phases. The relatively coarsened Zn<inf>2</inf>Mg phases were locally observed inside the ZnMgAl-alloy coating. The DIC strain analysis revealed that the strain was localized in the primary solidified Al phases and fine eutectic microstructure around the Zn<inf>2</inf>Mg phase. The results indicated high deformability of the multi-phase microstructure of the ZnMgAl-alloy coating.
