Abstract Realizing improved strength–ductility synergy in eutectic alloys acting as situ composite materials remains a challenge conventional systems, which is why high-entropy (EHEAs), newly-emerging multi-principal-element category, may offer wider possibilities. Here, we use an AlCoCrFeNi 2.1 EHEA to engineer ultrafine-grained duplex microstructure that deliberately inherits its lamellar nature by tailored thermo-mechanical processing achieve property combinations are not accessible...
The Ce46La5C49 alloy was first prepared in a 25 kg vacuum induction melting furnace. La-doped CeO2 nanopowders were then by hydrolysis and oxidation of at room temperature. These calcinated different temperatures order to improve their catalytic activities. lanthanum ions used partially replace the cerium lattice, forming solid solution lanthanum. Compared pure CeO2, thermal stability increased due doping. show enhanced CH4 performance.
In this paper, the effects of different melt spinning speeds on mechanical properties (TiZr)0.5(Ni0.6Cr0.1V0.1)2.1 amorphous ribbons were studied. Tensile tests specimens used to investigate behavior and ribbons. The cooling rate glass transition temperature was discussed. correlation between microstructure serrated flow in stress-strain curves also evaluated. addition, when speed 45 m/s, a large number dense uniform dimples appeared fractured surface specimens. Furthermore, characteristics...
The microstructure and room temperature magnetic properties for (Nd0.8Ce0.2)1.6Fe12Co2BZrx (x = 0-5) nanocomposite alloys prepared by melt-spinning method subsequent thermal annealing have been investigated. Zr addition has proved to result in relevant improvements the properties. enhanced coercivity Hcj of 6.02 kOe maximum energy products (BH)max 15.2 MGOe obtained at optimum Ta with content x 2 3, respectively. results X-ray diffraction (XRD) transmission electron microscope (TEM) indicate...
The melt-spun ribbons of LaFe11.5Si1.5Cx (x = 0, 0.1, 0.2, 0.3) compounds are prepared by the melt fast-quenching method. doping C is beneficial to nucleation and precipitation La (Fe, Si)13 phase, which indicated microstructure observation elemental analysis. Subsequently, LaFe11.5Si1.5C0.2 annealed at different times, phase composition, microstructures, magnetic properties investigated. 1273 K for 2 h achieved best properties, maximum isothermal entropy change with a value 9.45 J/(kg·K)...
In this paper, the magnetocaloric properties of Gd1-xTbx alloys were studied and optimum composition was determined to be Gd0.73Tb0.27. On basis Gd0.73Tb0.27, influence different Fe-doping content discussed effect heat treatment also investigated. The adiabatic temperature change (ΔTad) obtained by direct measurement method (under a low magnetic field 1.2 T) specific capacity calculation (indirect measurement) used characterize (x = 0~0.4) (Gd0.73Tb0.27)1-yFey (y 0~0.15), isothermal entropy...
