1. Effect of Melt Spinning on Microstructure and Corrosion Uniformity of Zn-Ag-based Alloy.
PMID:日期:2026-05-05Zinc (Zn) alloys are widely studied as biodegradable materials for interventional medical applications. However, Zn alloys produced by traditional casting and extrusion methods exhibit uneven corrosion resistance due to the presence of large intermetallic particles and a coarse microstructure. In this study, we demonstrate that melt spinning significantly refines the microstructure and intermetallics, thereby enhancing the alloy's corrosion uniformity. The grain size distribution is reduced from 3-11 μm to 0.8-1.2 μm, with an increase in the proportion of recrystallized regions and a decrease in crystal preferential orientation. Additionally, we report a simultaneous decrease in both the volume fraction and the number density of -AgZn nanoparticle precipitates after melt spinning. Mechanical testing reveals a yield strength of 396-408 MPa, an ultimate tensile strength of 410-420 MPa, and an elongation of approximately 16% for the melt-spun alloy. Additionally, this alloy demonstrates polarization resistance of 0.38 kΩ cm in its melt-spun condition, and very uniform corrosion progression. This favorable corrosion performance is attributed to the formation of a dense, stable passive layer that provides effective protection. This layer forms through the interaction of oxide and corrosion products in Hank's solution.

2. Systematic Study of TiC Nanoparticle Effects on the Fatigue Behavior of Zn and Zn Alloys.
PMID:日期:2025-09-10Zinc (Zn) is a promising material for biodegradable implants due to its moderate corrosion rate and superior biocompatibility over magnesium (Mg) and iron (Fe). However, its poor fatigue performance limits broader applications. While nanoparticles were discovered to enhance the fatigue performance of metals, the mechanisms remain underexplored. This study investigates nanoparticle-enabled mechanisms for fatigue improvement in Zn. Specifically, the microstructure, tensile, and fatigue performance of pure Zn and Zn nanocomposites containing 1 vol. % and 2 vol. % titanium carbide (TiC) nanoparticles were examined. Results demonstrated that TiC nanoparticles significantly enhanced fatigue resistance of Zn at room temperature (RT) and body temperature (BT). The improved fatigue performance was partly attributed to enhanced tensile strength. Further analysis, including Basquin's equation fitting and fatigue fracture surfaces examination, showed that TiC nanoparticles significantly enhance fatigue resistance by refining grain structure, impeding dislocation movement, altering crack propagation pathways, and promoting energy dissipation during debonding. Moreover, nanoparticle incorporation reduced the temperature sensitivity of Zn's fatigue behavior, ensuring more stable performance under elevated temperatures. Additionally, Zn nanocomposites like Zn-Al-Cu-TiC and Zn- Mg-TiC maintained suitable biocompatibility and corrosion rates. These findings highlight TiC nanoparticles as a powerful solution to overcome Zn's fatigue limitations for biodegradable medical devices.

3. Unravelling thermal history during additive manufacturing of martensitic stainless steel.
PMID:日期:2021-03-15thermal cycling neutron diffraction experiments were employed to unravel the effect of thermal history on the evolution of phase stability and internal stresses during the additive manufacturing (AM) process. While the fully-reversible martensite-austenite phase transformation was observed in the earlier thermal cycles where heating temperatures were higher than A, the subsequent damped thermal cycles exhibited irreversible phase transformation forming reverted austenite. With increasing number of thermal cycles, the thermal stability of the retained austenite increased, which decreased the coefficient of thermal expansion. However, martensite revealed higher compressive residual stresses and lower dislocation density, indicating inhomogeneous distributions of the residual stresses and microstructures on the inside and on the surface of the AM component. The compressive residual stresses that acted on the martensite resulted preferentially from transformation strain and additionally from thermal misfit strain, and the decrease in the dislocation density might have been due to the strong recovery effect near the Ac temperature.

5. {"_":"A novel and stable way for energy harvesting from BiTeSe alloy based semitransparent photo-thermoelectric module.","sub":["2","3"]}
PMID:日期:2020-12-30In this research, due to the present pandemic of COVID-19, we are proposing a stable and fixed semitransparent photo-thermoelectric cell (PTEC) module for green energy harvesting. This module is based on the alloy of Bismuth Telluride Selenide (BiTeSe), designed in a press tablet form and characterized under solar energy. Here, both aspects of solar energy i.e., light and heat are utilized for both energy production and water heating. The semitransparent PTEC converts heat energy directly to electrical energy due to the gradient of temperature between two electrodes (top and bottom) of thermoelectric cells. The PTEC is 25% transparent, which can be varied according to the necessity of the utilizer. The X-ray diffraction of material and electric characterization of module i.e., open-circuited voltage (V) and Seebeck coefficient were performed. The experimental observations disclose that in the proposed PTEC module with an increment in the average temperature (T) from 34 to 60 °C, results in the rise of V ∼ 2.4 times. However, by modifying the size of heat-absorbing top electrode and by increasing the temperature gradient through the addition of water coolant under the bottom electrode, an uplift in the champion device results in as increment of V ∼5.5 times and Seebeck coefficient obtained was -250 μV/C, respectively. Results show that not only the selection of material but also the external modifications in the device highly effective the power efficiency of the devices. The proposed modules can generate electric power from light and utilize the penetrating sunlight inside the room and for the heating of the water which also acts as a coolant. These semitransparent thermoelectric cells can be built-in within windows and roofs of buildings and can potentially contribute to green energy harvesting, in situations where movement is restricted locally or globally.

6. Welding and Additive Manufacturing with Nanoparticle-Enhanced Aluminum 7075 Wire.
PMID:日期:2020-09-05Aluminum alloy 7075 (Al 7075) with a T73 heat treatment is commonly used in aerospace applications due to exceptional specific strength properties. Challenges with manufacturing the material from the melt has previously limited the processing of Al 7075 via welding, casting, and additive manufacturing. Recent research has shown the capabilities of nanoparticle additives to control the solidification behavior of high-strength aluminum alloys, showcasing the first Al 7075 components processed via casting, welding, and AM. In this work, the properties of nanoparticle-enhanced aluminum 7075 are investigated on welded parts, overlays and through wire-based additive manufacturing. The hardness and tensile strength of the deposited materials were measured in the as-welded and T73 heat-treated conditions showing that the properties of Al 7075 T73 can be recovered in welded and layer-deposited parts. The work shows that Al 7075 now has the potential to be conventionally welded or additively manufactured from wire into high-strength, crack-free parts.

7. {"_":"Vibrational modes and quantum zero-point energy of hydrogen in ZrH and ZrH.","sub":["0.0155","2"]}
PMID:日期:2020-03-25We report on an inelastic neutron scattering study of the proton dynamics in ZrH and ε-ZrH. In particular, we present measurements of the incoherent dynamic structure factor, generalized vibrational density of states, and proton momentum distribution of these two materials. Our results are generally consistent with theoretical predictions of Elsässer et al. [Mat. Res. Soc. Symp. Proc. 221-226 (1997)]. They argued that the effective Born-Oppenheimer potential experienced by the hydrogen atoms in ε-ZrH is nearly isotropic and harmonic at energies below 0.3 eV, but becomes anisotropic and anharmonic for higher energies. At low temperatures, the proton momentum distribution is dominated by the quantum-mechanical ground state of the protons. We find that it assumes a Gaussian shape, consistent with the concept that the potential surface is approximately harmonic for small displacements of the hydrogen atoms. However, the anharmonicity of the potential becomes readily apparent in the excited states of the hydrogen atoms, as the harmonic approximation breaks down in the description of the multiphonon bands.

8. Focused Ion Beam-Induced Displacive Phase Transformation From Austenite to Martensite during Fabrication of Quenched and Partitioned Steel Micro-Pillar.
PMID:日期:2020-01-01We report evidence of a displacive phase transformation from retained austenite to martensite during preparation of quenched and partitioned steel micro-pillars by using a focused ion beam (FIB) technique. The BCC phase produced by the FIB damage was identified as martensite. The invariant-plane strain surface relief associated with the martensitic transformation was observed in the retained austenite phase immediately after a FIB scan of the surface with the Ga ion beam. Use of a low acceleration voltage appears to lower the probability of the phase transformation, while a decrease of the acceleration voltage will result in an increase of the total milling time required to prepare a micro-pillar. This report addresses challenges related to the preparation of austenite micro-pillars by a conventional FIB technique.

9. {"_":"Comparison of anion and cation dynamics in a carbon-substituted -hydroborate salt: H and Na NMR studies of solid-solution Na(CBH)(CBH).","i":["closo"],"sup":["1","23"],"sub":["2","9","10","11","12"]}
PMID:日期:2019-09-01The hexagonal mixed-anion solid solution Na(CBH)(CBH) shows the highest room-temperature ionic conductivity among all known Na-ion conductors. To study the dynamical properties of this compound, we have measured the H and Na nuclear magnetic resonance (NMR) spectra and spin-lattice relaxation rates in Na(CBH)(CBH) over the temperature range of 80-435 K. It is found that the diffusive motion of Na ions can be described in terms of two jump processes: the fast localized motion within the pairs of tetrahedral interstitial sites of the hexagonal close-packed lattice formed by large anions and the slower jump process via octahedral sites leading to long-range diffusion. Below 350 K, the slower Na jump process is characterized by the activation energy of 353(11) meV. Although Na mobility in Na(CBH)(CBH) found from our NMR experiments is higher than in other ionic conductors, it appears to be an order-of-magnitude lower than that expected on the basis of the conductivity measurements. This result suggests that the complex diffusion mechanism and/or correlations between Na jumps should be taken into account. The measured H spin-lattice relaxation rates for Na(CBH)(CBH) are consistent with a coexistence of at least two anion reorientational jump processes occurring at different frequency scales. Near room temperature, both reorientational processes are found to be faster than the Na jump process responsible for the long-range diffusion.

10. Mn Doped AZIS/ZnS Nanocrystals (NCs): Effects of Ag and Mn Levels on NC Optical Properties.
PMID:日期:2018-10-15In this work, Mn-doped AZIS/ZnS NCs were prepared using a nucleation doping approach with the tuning of Mn and Ag levels in their synthesis. The optical properties of Mn:AZIS/ZnS NCs are found to be significantly affected by Ag and Mn levels. Specifically, more Ag and Mn atoms in Mn:AZIS/ZnS NCs cause their fluorescence red-shift, and as the Ag or Mn level reaches a high threshold, the fluorescence lifetime of Mn:AZIS/ZnS NC has a significant drop. The reasons for the effects of Mn and Ag levels on NC optical properties were explored and discussed. Through this study, it is also found that with certain Ag and Mn levels in synthesis, some Mn:AZIS/ZnS NCs present optimal optical properties including high brightness (QY > 40%), long fluorescence lifetime (> 1.2 ms), low energy for excitation (excitable at 405 nm), and no reabsorption. The feasibility of the optimized NCs for time-gated fluorescence measurement using a portable/compact instrument was further demonstrated, which indicates the application potential of the NCs in time-gated biosensing including point-of-care testing. Notably, this study also discloses that Mn:AZIS/ZnS NCs with different lifetimes can be achieved by tuning Mn and Ag levels in synthesis, which may further broaden the applications of Mn:AZIS/ZnS NCs in multiplexing detection/measurement.
