This report investigates the effect of firing temperatures on the phase formation, microstructure, electrical, and energy storage properties of lead-free Sr0.3(Bi0.7Na0.67Li0.03)0.5TiO3 (SBNLT) ceramics, synthesised by combustion technique. The samples were calcined between 700°C and 900°C for 2 h and sintered between 1100°C and 1200°C for 2 h. The ceramics exhibited coexisting rhombohedral and tetragonal phases, which were confirmed by the Rietveld refinement technique. A morphotropic phase boundary (MPB) of the rhombohedral and tetragonal phases, with a ratio of 49:51, was obtained at the sintering temperature of 1175°C. The highest maximum dielectric constant (ε max = 4667), polarisation (P max = 28.80 µC/cm2) and energy density (W = 0.95 J/cm3), with a breakdown strength of 70 kV/cm, were achieved from the sample sintered at 1175°C.

A photo-deposition method was developed to synthesise argentous oxide/calcium aluminate nanocomposites (Ag2O-CAONCS) with orthorhombic Ca5Al6O14 and cubic Ag2O phases. Micro-morphology, micro-structure, optical, and visible-light catalytic properties were investigated via different techniques. Ag2O enhances visible-light absorption performance and decreases the band gap of the Ag2O-CAONCS. About 20 mL crystal violet (CV) dye (10 mgL–1) is totally degraded using 20 mg Ag2O-CAONCS under sunlight irradiation for 20 min. The enhanced photocatalytic activity of the Ag2O-CAONCS towards CV under sunlight irradiation is ascribed to the reduction of the band gap, improvement in visible-light absorption and inhibitation role of carriers recombination by Ag2O. The high, stable visible-light catalytic activity makes Ag2O-CAONCS promising photocatalysts for removing organic pollutants.

The effect of the pre-friction extrusion microstructure of AZ91 billet on the microstructure, mechanical properties, and corrosion resistance of AZ91-bioactive glass surface composite rods was investigated. The results show that friction extrusion on AZ91 alloy billet with cast microstructure results in agglomerated bioactive glass particles in the composite rod microstructure. Compared to as-cast AZ91 alloy, friction extrusion on AZ91 alloy billet with cast microstructure results in 93% more corrosion resistance. Also, friction extrusion on AZ91 alloy billet with extruded microstructure leads to a gradient AZ91-bioactive glass composite rod with ultimate tensile strength, yield strength, and corrosion resistance of 9, 2, and 74% higher than AZ91 alloy rods, respectively.

CoCrFeNiMnTi x (x = 0.5, 1.0, 1.5, 2.0 in atomic ratio) high entropy alloy (HEA) coatings were prepared on 304 stainless steel by laser cladding. Experimental results showed that the CoCrFeNiMnTi x HEAs constituent phase evolved from a single FCC phase for the HEA to FCC + BCC + Intermetallic + Laves phases with the addition of Ti element. The CoCrFeNiMnTi x coatings exhibited an increasing microhardness from 412.42 HV to 573.97 HV. Accompanying the increase in microhardness, the wear resistance was proportional to the hardness of the coating, which met Archard’s relationship. In addition, the corrosion resistance of the CoCrFeNiMnTi x coatings displayed an increased tendency firstly and then decreased with the addition of Ti element. And, the HEA coating with x = 1.0 possessed the highest corrosion resistance as indicated by the lower corrosion current density, high charge transfer resistance and high pitting potential.
采用激光熔覆技术在304不锈钢表面制备了CoCrFeNiMnTi x (x = 0.5, 1.0, 1.5, 2.0)高熵合金(HEA)涂层。实验结果表明，随着Ti元素的加入，CoCrFeNiMnTi x HEAs的组成相由HEA的单一FCC相演变为FCC + BCC +金属间化合物+ Laves相。CoCrFeNiMnTi x涂层的显微硬度从412.42 HV提高到573.97 HV。随着显微硬度的增加，涂层的耐磨性与硬度成正比，符合Archard关系。此外，随着Ti元素的加入，CoCrFeNiMnTi x涂层的耐蚀性呈现先增加后降低的趋势。当x = 1.0时，HEA涂层具有较低的腐蚀电流密度、较高的电荷转移电阻和较高的点蚀电位，具有较高的耐蚀性。

This study used a unique, low-power (2.8 kW) gas tunnel plasma spray and γ-Al2O3 feedstock powder to deposit a thin Al2O3 coating (<2 µm) on mild steel substrate. By optimising the plasma gas flow rate, powder feed rate, spraying time, and distance, a dense and homogeneous Al2O3 coating was obtained at a very high deposition rate (150 nm/s). During plasma coating, the high energy density plasma transforms the γ-Al2O3 powder into a highly crystalline α-Al2O3 as the predominant microstructure of the coating. The performance of the Al2O3 coating on mild steel was then evaluated preliminary using a linear sliding wear test against a chrome-steel ball, with the results indicating an 18–26% reduction in wear when compared to the uncoated substrate.

The under-oxidized condition (insufficient internal oxidation) for Ag-0.20Mg-0.19Ni (in wt-%) alloy was conducted at 650°C for 2 h, and the microstructural evolution in the alloy was investigated. The average grain size of the oxidized region and the unoxidized region are 3.82 µm and 3.86 m, respectively. The results suggest that the oxides enriched at grain boundaries do not hinder grain growth in the under-oxidized condition. The hardness of the oxidized region increases significantly, while the hardness of the unoxidized region decreases due to recrystallization. Both the number and the distribution area of MgO precipitates at the grain boundaries are increased with the internal oxidation time. Additionally, small MgO precipitates merge to form larger oxide particles with the internal oxidation time.

ABSTRACT This study employed metronidazole skeletons based on the target branched molecules (TBMs) for achieving efficient anti-corrosion of mild steel in HCl solution. In contrast, the reference linear molecules (RLMs) carrying a single metronidazole framework were also made. The excellent corrosion resistance performance of the target dendrimers for mild steel electrodes in HCl solution was demonstrated. It is shown that the TBMs displayed a superior anti-corrosion effect for mild steel over RLMs in HCl medium at 298 K (at 0.15 mol/L, TBM1, 97.70% versus RLM1, 90.89%). It is shown that the standard Gibbs free energy changes of the adsorption of the TBMs on mild steel surface are below −33 kJ/mol (TBM1, −34.58 kJ/mol), thus an enhanced adsorption film was formed.

The potentials of artificial neural network (ANN) modelling as a potent machine learning approach for investigating the hot deformation behaviour of high-entropy alloys (HEAs) and multi-principal element alloys during thermomechanical processing are assessed and reviewed. Flow stress of CoCrFeNiMn (FCC Cantor alloy), HfNbTaTiZr (BCC refractory alloy), AlCoCuFeNi, and Al x CoCrFeNi alloys is accurately predicted based on the deformation temperature, strain rate, and strain. Moreover, in comparison with the limited experimental dataset, a significantly larger output dataset can be generated by ANN to gain valuable insights such as prediction of flow stress (and whole dynamic recovery/recrystallisation flow curves), elucidating the microstructural mechanisms such as dynamic precipitation reactions, and obtaining hot working parameters (e.g. deformation activation energy) for different ranges of deformation conditions.

Additive manufacturing (AM) allows for the fabrication of custom orthopaedic implant devices which have complex geometries and similar mechanical properties to bone. This paper reviews the corrosion, fatigue and wear properties of AM Ti alloys to confirm their safety for use in orthopaedic implants. Specifically, AM Ti lattice geometries are highlighted due to their improved osseointegration and better modulus matching with that of bone, making them an attractive option for more durable implant devices. Finally, the properties of current implants made via AM are compared with that made via conventional manufacturing methods to confirm their overall safety.

ABSTRACT Joining of Ti and Fe-based alloys is challenging due to the formation of deleterious phases at the interface. Since fusion welding is unsuitable for the purpose, over the years, many solid-state welding techniques have been tried. This review provides a comparison of different solid-state joining methods used for Fe/Ti alloys with focus on the structural transformations in base materials, effect of process parameters on interface microstructure, its evolution and kinetics with thermal aging and structure–property correlation. Structural transformations in diffusion couples (near-equilibrium condition) are compared with those in weldments and a perspective is provided on the role of defects and alloying additions in enhancing/retarding reaction zone formation under both equilibrium and non-equilibrium conditions.
