Summary: Nanostructured metallic multilayers (NMMs) have been widely studied as efficient accident-tolerant fuel (ATF) materials. In this work, Cr75Al25/Zr (CA/Zr) NMMs with different layer thicknesses were prepared and subjected to He+ implantation. The results showed that the interface of the NMMs changed from crystalline/crystalline to crystalline/amorphous when the thickness decreased to 25 nm, accompanied by a transition from strengthening to softening behavior. The study also found significant irradiation hardening in the NMMs, which was attributed to the interactions between He bubbles and dislocations, as well as the increased back-stress hardening at different thicknesses.

Summary: The study investigates the evolution of the non-dendritic equiaxed zone (EQZ) and its effect on the tensile properties of tungsten inert gas (TIG) welded joints of dissimilar A6061-T6 and A6082-T6 materials. The presence or absence of EQZ significantly influences the strength of the welded joints, with A6082-T6 interface showing higher strength compared to A6061-T6 interface due to the absence of EQZ.

Summary: The mechanical properties of nanocrystalline pure Ni films degrade due to grain coarsening when exposed for a long time. In order to improve the mechanical properties, Mo-W co-doped Ni/Ni3Al multilayered structures were constructed. The average grain sizes and crystallinity degrees decrease when the individual layer thickness is below 40 nm. At 40 nm, nano-twins are observed due to the reduction of stacking fault energy. The hardness of the multilayers is enhanced and the elastic modulus is reduced. The best mechanical performance is observed in the Mo-W-doped Ni/Ni3Al multilayer with a thickness of 10 nm.

Summary: Ni-based multilayered film with 5 at.% Mo and 5 at.% W content has been synthesized. The individual layer thickness was modulated from 10 nm to 160 nm. The multilayer exhibited excellent thermal stability and improved hardness with reduced individual layer thickness. The 40 nm individual layer thickness resulted in superior toughness due to crack deflection and less brittle phase precipitation.

Summary: In this study, Mo/VC multilayers with constant period and different modulation ratios were deposited by dc magnetron sputtering. The microstructure and mechanical properties of the multilayers were investigated using XRD, TEM, Nanoindent, and Microindent methods. The results showed that the hardness remained high while the toughness increased with changing modulation ratio. The enhanced properties were attributed to the interfaces and lamellated structure. The formation mechanism of the interface was also determined using first-principles method.

Summary: For the first time, Al-Nb-Ti-B inoculant was added to Mg-9Al-1Zn (AZ91) alloy. The MB2 particles in the inoculant with (TiB2)NbB2 core-shell structure have a good lattice matching relationship with AZ91 alloy, thus acting as effective heterogeneous nucleation centers of the melt of AZ91 alloy and leading to significant refinement of grains and microstructures. The best refining effect can be achieved when the adding content of the inoculant reaches 0.8 wt%, and the average grain size is refined from the original 80.4 μm to 18.2 μm. With the decrease of grain size, the tensile strength, elongation, and damping increase. The correlated mechanisms were discussed.

Summary: The microstructural evolution and mechanical properties of Cu/Nb NMMs under different annealing temperatures were investigated. The results showed that the nanolayered structure of the NMMs is maintained at temperatures below 800°C, but thermal instability occurs at 1000°C, leading to the disintegration of the nanolayered structure. Tensile tests revealed enhanced strain hardening and improved ultimate tensile strength and elongation in the 1000°C annealed samples.

Summary: The design of powder metallurgy components made of advanced ceramic materials requires information on mechanical behavior, which affects lifetime, wear, and friction performances. Sintered materials' microstructure depends on sintering cycle variables and plays a significant role in final properties. NbC has high hardness and melting point, but its sinterability and hardness may be influenced by stoichiometry. Experimental analyses showed that the relationship E/H is a key factor in governing tribological properties in this study, and wear and friction behaviors were reproduced by numerical analysis to understand the system performance.

Summary: This study analyzed the adhesion of thick amorphous carbon coatings by considering the combination of metallic chromium as a bond layer and a carbon bombardment step. The results showed that a lower bias voltage increased the sp3 content of the carbon transition layer, improving the adhesion. An increase in the carbon cathode current also enhanced the adhesion by increasing the thickness of the mixing layer. Additionally, reducing the bombardment temperature improved the adhesion. A diagram was proposed to illustrate the expected behavior of adhesion based on the available results.
