High-performance structural materials are critical to the development of transportation, energy, and aerospace. In recent years, newly developed high-entropy alloys with a single-phase solid-solution structure have attracted wide attention from researchers due their excellent properties. However, this new material also has inevitable shortcomings, such as brittleness at ambient temperature thermodynamic instability high temperature. Efforts been made introduce small number intermetallic...
Copper/diamond composites have been proposed as thermal management materials for high performance electronic devices. However, their conductivity (TC) is limited by the weak interfacial bond between copper and diamond, due to poor chemical affinity. To enhance TC, tungsten (W) was explored an effective element, reacting with diamond form a carbide interface diamond. This study involved fabricating copper/55vol%W-coated via hot forging at temperatures of 800 °C, 950 1050 °C. Additionally,...
The excellent “mirror” effect of medium and high-strength aluminum alloy profiles from the 6-series, achieved through anodizing, is highly valued by customers. Metallographic analysis a key method for predicting anodizing effect. However, traditional metallographic methods suffer unstable accuracy low efficiency. To address these issues, this paper successfully develops grading system constructing dataset integrating computer vision with machine-learning techniques. Based on grain...
This study aims to develop Ti–Cu–Mn alloys with antibacterial capability for reducing the possibility of bacterial infection during biomedical implant surgeries. Ternary were designed be manufactured via powder metallurgy, which has intrinsic manufacturing, economic, and environmental benefits. The amount each alloying elements was limited prevent formation brittle phases. It is found that selected compositions Cu (0.5-5 wt.%) plus Mn (0.25-2.5 can successfully achieving microstructures,...
Transition metal based high entropy alloys (HEAs) are often used in electrocatalytic (water electrolysis) applications due to the synergistic effect operating among its constituent elements and unpaired electrons d orbitals of concerned metal. In this study, a low cost NiMnFeCu alloy was successfully synthesised using combined techniques mechanical milling (MA) vacuum sintering. X-ray diffraction analyse phase composition, optical microscopy, scanning electron microscopy were characterise...
The hot workability of metallic materials is significantly dependent on its ability to form plastic without cracking and fracturing. In this work, the behavior powder metallurgy (PM) Ti-5Al-5Mo-5V-3Cr (Ti-5553) alloy, consolidated from mixture, at a deformation temperature range 600 °C–850 °C strain rate 0.1 s−1–10 s−1, was investigated through isothermal compression tests. as-cast ingot (IM) Ti-5553 700 also for comparison. Results suggested that PM alloy had better workability, with larger...
In this work, three as-cast L12-type HEIs with different content of Co element were carefully examined combined TEM, SEM and XRD technologies. The main matrix alloys was L12 ordered phase, Si,Ti-rich grain-boundary precipitate phase generated the addition Co. Co1 alloy, distinct dual-phase core–shell structure found within grain due to precipitation extra FCC disordered secondary which leads a better strength-plasticity combination (compressive strength 3441 ± 50 MPa, fracture strain 46.0...
This paper focuses on the research of a new high-speed DC switch repulsion mechanism with experimental and simulation methods. Multi-physical equations reflecting transient electromagnetic field, electric circuit, mechanical motion material deformation are coupled in calculation. For reason accuracy, skin effect proximity caused by current coil also taken into account. According to results, which indicate several key parameters severely affecting speed, is developed. By test motion, its...
The demand for heat-resistant steel has increased owing to its utility in numerous devices that must withstand high steam pressures and temperatures, such as turbine rotors blades ultra-supercritical power plants. It is inevitable join heat-resistance part by welding method, so it important maintain the toughness of weld metals. In this study, microstructure, low-temperature impact toughness, fracture surface as-welded post-weld heat treatment (PWHT) 2.25Cr-1Mo-0.25V metal were investigated....
