Designing compositions for novel alloys requires a fundamental grasp of the role each alloying element in its properties. This study delves into influence elements Ultra-High Strength Steels on essential high-temperature properties, including thermoelasticity, thermal stress, and strength, utilizing first-principles phonon calculations. These properties are pivotal steels used applications. Our investigation quantitatively forecasts impact elastic providing valuable insights advanced alloy...
Fe-Cr-C-B wear-resistant steels are widely used as alloys in harsh environments. The M3X (M = Fe, Cr; X C, B) cementite-type material is a commonly strengthening phase these alloys. This study investigated the mechanical properties of cementite (Fe, Cr)3(C, using first-principle density functional theory. We constructed crystal structures with different concentrations Cr and B. bulk modulus, shear Young’s Poisson’s ratio, hardness were calculated, comprehensive property database based on...
The CaTa0.8WO6 ceramic was fabricated by a solid-state reaction for thermal/environmental barrier coating (Thermal and Environmental Barrier Coating) applications, the microstructures, mechanical thermal properties were investigated. result showed has lower conductivity (1.05 W·m−1·K−1 at 900 °C) than 8 wt.% yttria-stabilized zirconia doped Ta-based ceramics with Mg2+, Yb3+, Zr4+ Nb5+, indicating that hexavalent tungsten element W6+ doping effectively reduces improves insulation performance...
First-principles calculations were used to investigate the stability, electronic structure, elastic and lattice thermal conductivity of FeS 2 polymorphs ([Formula: see text]-FeS, [Formula: text]-FeS , ). The calculated parameters in agreement with experimental results. results showed that these Fe-S binary compounds are thermodynamically mechanically stable. anisotropies exhibited by 3D modulus ball 2D projections. Among all five compounds, compound has largest bulk Young’s hardness....
Fe2B was widely used as the strengthening phase and wear-resistant skeleton in high boron iron-based composite. The weak interfacial bonding of Fe2B/Fe interface is one main reasons for poor mechanical properties composite, which motivated us to develop a strain stiffening strategy chemical bonds improve bond strength elongation interface. effects alloying elements Ti, Cr, Mn, Co, Ni, Cu, Y, Nb, Mo, Ta, W on Fe(001)/Fe2B(001) were investigated through first-principles calculations....
Dust aggregates in plasma charge, which makes it difficult to study the propagation of electromagnetic wave it. While order influence charged dust space detection, some work must be done for characteristic Based on discrete dipole approximation (DDA), scattering is studied. At beginning, DDA theory and expressions coefficients by a single sphere are introduced simply. Nextly, considering charges, polarization each method corrected sphere. Thirdly, models we using simulated two different...
In the high density microwave multi-chip module (MMCM), external interconnection between components and internal layers affect performance, size cost of MMCM directly. One challenges is to solve problem parasitic parameters. this paper parameters via in LTCC circuit board are used match structure gold wire bonding innovatively, which results better matching smaller wider working frequency bandwidth. Besides, by combining DGS, performance buried stripline could be debugged externally.
