Abstract ：
The diverse shapes and multi-component characteristics of complex carbides in nickel-based superalloys play a crucial role in determining their mechanical properties. However, relying solely on experimental evaluations poses challenges, making analog simulations essential. This study investigates the structural, mechanical, and electronic properties of skeletal and blocky carbides in the DZ125 superalloy using first-principles calculation and experimental methods. The carbides analyzed include Ti0.125Ta0.625Hf0.25C and Ti0.125Ta0.25Hf0.625C, which differ in their Ta and Hf ratios. The results indicate that Ti0.125Ta0.625Hf0.25C exhibits superior mechanical properties compared to Ti0.125Ta0.25Hf0.625C, along with enhanced fracture toughness and higher energy requirements for crack propagation. Electronic characteristic analysis reveals that Ti0.125Ta0.625Hf0.25C possesses greater thermodynamic stability due to the presence of more valence electrons in Ta atoms, which form stronger covalent and metallic bonds. Additionally, quasi-in-situ tensile testing confirms that skeletal carbides exhibit higher cracking resistance compared to blocky carbides. This study enhances our understanding of the stability of these carbides and provides valuable insights for the design and optimization of DZ125 superalloys.

Abstract ：
Extremely rapid heating and cooling rates during the additive manufacturing (AM) process generate complicated thermal cycles, which affect the microstructure evolution and ultimate mechanical properties of the alloy. In this paper, FGH96 blocks with a height of 6 mm were prepared by selective laser melting (SLM) and the microstructure was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Comparing specimens of varying heights, it was found that subsequent thermal cycles (STC) coarsened some solidified grains and accelerated the grain growth along the build direction, together with an increase in texture intensity and high-angle grain boundaries (HAGBs). After coarsening the grains in the middle portion of the built block, finer grains were observed near the top area due to a faster cooling rate. There were numerous dislocations in the grain because of the occurrence of unequal internal tension. In the middle of the sample with stable thermal cycles, the dislocations were both perpendicular to the grain growth direction and 45 degrees off it. In spite of the texture characteristics, the segregation of elements was also found to be influenced by thermal cycling. Inherent reheating leads to the increase in the Laves phase and the decrease in the gamma' phase as subsequent deposition. This was also one of the reasons why the microhardness of the sample decreased as the building height and the other reason being the decrease in the solution treatment of the later sediments.

Abstract ：
Fabry-Perot structures comprising metal/interference medium/metal have attracted considerable attention as lithography-free and scalable color reflectors, as such structures can selectively absorb electromagnetic waves in the visible range to produce vivid reflected colors. However, traditional methods for producing high-saturation reflected colors generally use a narrow full width at half-maximum (fwhm) or high reflectivity. This work proposes a nanoscale multi-unit-stacking structure based on a Ge2Sb2Te5 (GST)-ITO interference unit to obtain high-saturation colors combined with fwhm and reflectivity. Finite element simulations and experimental measurements reveal that the additional absorption bands introduced by the stacking interference units reduce the fwhm of the peak and increase reflectivity, thus improving the saturation. Furthermore, adjustments in the number of stacking cells lead to changes in the saturation but have a negligible effect on the hue. The use of germanium-antimony-tellurium (also denoted as GST) as a phase-change material can facilitate further adjustments in the optical tenability of the structure upon phase transition, indicating certain potential applications. Moreover, the structure exhibits shortwave infrared shielding owing to the destructive interference of the GST layer. Additionally, the application of this structure in color printing was demonstrated. This study simplifies the design process of highly saturated colors, circumvents expensive preparation processes, and offers the possibility of shortwave infrared shielding. The nanoscale structures described herein indicate new opportunities in the field of color coatings, intelligent windows, and decorations.

Abstract ：
Heterostructural materials have the advantage of extreme low switching energy between states and hence are expected to be applied in photonic devices, whose optical performances are vital to explore in advance. In this paper, crystal structures of TiTe2/Sb2Te3 heterostructural films and their effects on optical properties were clarified from the aspects of in-plane strain, resonant bonding and charge redistribution by experiments and first principle simulations. Larger strain in Sb2Te3 sublayer tended to decrease reflectivity and refractive indexes, while huge resonant bonding effect was beneficial to improve the optical parameter deviations. Charge analyses showed that crystalline optical property variations were actually deriving from the electron redistribution differences especially near the heterostructural Te center dot center dot center dot Te gap, which also accounted for experimental reflectivity order. Finally, based on the resonant bond effects and surrounding electron density after stimuluses, five optical levels with identifiable optical contrasts (n and Delta R) were achieved in 1/2 model for uses. The present study sheds new light on optical properties of TiTe2/Sb2Te3 and paves the way for potential multi-state applications of heterostructure in photonic and storage devices.

Abstract ：
Phase-change materials (PCMs) provide an alternative avenue for modulating the adjacent layer property through interfacial effect, which sometimes is more effective than the traditional methods. Here, a systematic study of the phase-change induced control of FMR resonance field in Si/GeSbTe/FeCoB heterostructures is presented. We show that different crystalline phases induced by thermal anneal in GeSbTe/FeCoB films contribute to large shifts in resonance field of FeCoB up to 15 mT. The correlation between GeSbTe phase change and anisotropic field of FeCoB is confirmed from the GeSbTe film morphology dependent of stress. These results propose a method of phase-change induced control of FMR resonant field and ferromagnetism in PCM/ferromagnetic alloy film heterostructures by controlling interface roughness, which can be introduced in the optimization of ferromagnetic alloy film parameters and development of high functioning magnetic devices.
