Abstract The migration of twin boundaries plays a crucial role in the formability TiAl alloys at low temperatures. In this study, dislocation bow-out pair-mediated was systematically investigated. A model describing interaction Shockley pairs developed based on theory dislocations. thermodynamics bowing were thoroughly examined, revealing formation mechanisms two types bow-outs terms their energy and stress field interactions. critical angle, ϕc, proposed as criterion for transition from...
This study focused on analyzing the changes in microstructure and composition evolution of plasma electrolytic oxidation (PEO) electroless copper–PEO composite (Cu/PEO) coatings both prior to following irradiation. Additionally, corrosion resistance tribological properties these were assessed. Post-irradiation, PEO coating exhibited a 5% reduction porosity, electrochemical impedance spectroscopy (EIS) tests indicated notable enhancement short-term resistance, with low-frequency 106 Ω·cm2...

Extensive first-principles calculations have provided insights into electronic structure, bonding and superconducting properties Ti. transition temperature ( T c ) for Ti pressure estimated within framework BCS theory to be about 17.5...
The size effects in metal forming have been found to be crucial micro-scale plastic deformation or micro-forming processes, which lead attenuation of the material's formability due increasing heterogeneity flow. use an electric field during has shown relieve effects, enhance formability, modify microstructure, etc. Consequently, these electric-assisted (EA) processes seem bring many potential benefits that need investigated. Accordingly, here we investigated influence on describe fracture...
Developing bio-inspired functional surfaces on engineering metals is of extreme importance, involving different industrial sectors, like automotive or aeronautics. In particular, micro-embossing one the efficient and large-scale processes for manufacturing textures metallic surfaces. However, this process faces some problems, such as filling defects die breakage due to size effect, which restrict technology components. Electrically assisted micro-forming has demonstrated ability reducing...
Ultrasonic vibration (UV) is widely used in the forming, joining, machining process, etc. for acoustic softening effect. For parts with small dimensions, UV limited output energy very suitable microforming process and has been gaininf more attention. In this investigation, UV-assisted uniaxial tensile experiments were carried out utilizing GB 5052 thin sheets of different thicknesses grain sizes, respectively. The coupling effects specimen dimension on properties material analyzed from...
Texture surface containing both micro-pits and a thin carbon coating was produced using laser texturing magnetic-control vacuum sputtering. Tribological properties of the laser-textured coated with were experimentally investigated at low-temperature (8–10 °C) under starved lubricated conditions ring-on-ring test rig. The results indicated that combined (textured + coating) exhibited low wear intensity friction coefficient conditions, while moderate observed lubrication as compared smooth,...
The expected explosive traffic has forced the fifth-generation (5G) mobile communication system to be ultra-dense networks (UDNs). Driven by diverse applications, flexible resource scheduling encounters novel challenges. Resource issue is a large-scale optimization problem with high complexity and computational cost, which always leads nearly-optimal solution instead of truly-optimal one. Moreover, specific for partial types, cannot well support quality-of-service (QoS) demands in terms...
Bent micro-tubes have been frequently applied in electronics, medical devices and aerospace for heat transfer due to the increasing flux high-density electric packages. Rotary-draw bending (RDB) is a commonly used process forming tubes its versatility. However, control of defects key problem micro-tube terms wall thinning, cross-sectional deformation wrinkling.

Abstract In this paper, the effect of hydrogen placement on microdynamic wear mechanism high niobium-titanium-aluminum alloys is investigated. Corresponding decreases and increases in loading force displacement amplitude cause microslip behavior alloy to change from partial slip mixed slip. Slip type fire complete when you, friction coefficient fluctuates. The average hydrogen-placed small compared with that non-hydrogen-placed alloys, maximum marks are not obvious, oxidative weak. main...
