Special attention is paid to the effect of electrodeposition parameters and electrolyte composition on the microstructure, morphology, and mechanical/functional properties of the HEA coatings. It is demonstrated that the majority of researches has been focused on fabricating CoCrFeMnNi- and AlCrFeMnNi-based HEAs, with the addition of a few other elements by galvanostatic and potentiostatic techniques using both direct and pulsed current deposition modes. The fabricated HEA coatings exhibited different microstructures ranging from amorphous to nanocrystalline structures, exhibiting interesting magnetic, catalytic, and mechanical properties. Furthermore, we show that, while the possibility of fabricating metal matrix nanocomposite coatings using electrodeposition has been demonstrated, the fabricated composite coatings are mainly limited to transition element-based HEAs reinforced by graphene oxide and carbon nanotubes. Finally, several new directions and potential challenges such as electrochemical deposition of refractory HEAs and metal matrix composites reinforced by HEAs or high-entropy ceramics, as well as theoretical aspects of electrodeposition of HEAs and introducing machine learning to speed up the fabrication of novel coatings and optimize the processing parameters, are discussed.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 3","pages":"1005 - 1028"},"PeriodicalIF":2.1,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The alloys with moderate Ni content (6 ≤ x ≤ 8 at.%) are the FCC single-phase solid solutions, whereas the alloys with a less Ni (x ≤ 4 at.%) display a FCC + hexagonal close-packed (HCP) dual-phase structure due to thermally induced martensitic transformation.

The pre-strained single-phase Cr20Mn20Fe20Co34Ni6 alloy (x = 6 at.%) exhibited the highest recovery strain of 1.2% in the Cr20Mn20Fe20Co40−xNix system.

However, the presence of cracks and holes at the interface of these clad plates can adversely affect their strength and sealing performance. To mitigate the occurrence of such defects, explosive welding experiments were conducted on titanium and aluminum plates by varying the welding parameters. The experimental results reveal that the explosive welding interface of Ti/Al exhibits a regular corrugated shape, which tends to flatten due to aluminum’s low melting point and strength. Notably, when the welding parameters do not exceed collision velocity (V_{p} le 839;{text{m/s}}) collision angle (beta le 17.24^circ ), there are no discernible vortex holes at the interface, and the melting zone remains small. The melting zone at the interfaces of different welding parameters contains various intermetallic compounds. Although the shear strength of the titanium–aluminum welding interface surpasses that of aluminum, it is unstable due to the influence of titanium content and the presence of crack holes. Simulations of the welding process using AUTODYN indicate that the derived trend of ripple morphology changes in the simulation interface offers valuable reference for the experiment.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 4","pages":"1816 - 1824"},"PeriodicalIF":2.1,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimization of optical properties is very important for high device performance, and film thickness is a significant factor affecting the optical parameters. In this work, thin films of CdS:In were deposited by spray pyrolysis (SP) technique on glass substrates at substrate temperature Ts = 490°C. The films were characterized using X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX), and ultraviolet-visible (UV-vis) spectroscopy. The films presented a polycrystalline structure and mixed (cubic and hexagonal) phase. The transmittance of the films was measured at room temperature and used to deduce the optical parameters: absorption coefficient, extinction coefficient, refractive index, the real and imaginary parts of the dielectric constant, and the energy loss. A redshift of the absorption edge, which increases with film thickness, was observed. It was found that the extinction coefficient and energy loss decrease with film thickness, while the refractive index increases with film thickness, and this increase becomes faster with decreasing wavelength of incident light.

However, it is difficult to optimize the heat treatment process of Al-Si-Cu-Mg cast alloys because of the different solubilities of Al2Cu and Q-Al5Cu2Mg8Si6. In this study, the parameters of the heat treatment process were optimized by using thermal simulation and experimental, and the microstructure evolution during the solid solution process was studied. The results show that the dissolution temperatures of low melting point eutectic phase Al2Cu and Q-Al5Cu2Mg8Si6 are 502°C and 539°C by using DSC. Spherical Al2Cu phase is easily dissolved, and irregular Al2Cu phase and Q-Al5Cu2Mg8Si6 phase are not easily dissolved under the one-step solution treatment. However, the two-step solution treatment makes the Q-Al5Cu2Mg8Si6 phase dissolve, which improves the solid solution degree of the alloy. The spheroidization degree of eutectic Si is the highest under the optimum one- and two-step solution process. The microhardness was the highest (76.4 ± 1.2 HV, 95.6 ± 2.0 HV).
