Powder bed fusion (PBF) is a promising but challenging method for additive manufacturing of magnetocaloric Ni-Mn-Sn Heusler alloys, due to the material's inherent brittleness. To produce crack-free near-net-shape parts from prealloyed gas atomized 47.2Ni-39.2Mn-13.0Sn powder, electron beam powder (PBF-EB/M) with stress-reducing spot melting scanning strategy was successfully employed. The same identical-sized also processed using laser (PBF-LB/M) comparison. Notably different evaporation,...
Abstract High entropy alloys (HEAs) have a wide range of applications across various fields, including structural engineering, biomedical science, catalysis, magnetism, and nuclear technology. Nanoscale HEA particles show promising catalytic properties. Nevertheless, attaining versatile composition control in nanoparticles poses persistent challenge. This study proposes the use pulsed laser ablation liquids (PLAL) for synthesizing using equiatomic CoCrFeMnNi targets with varied preparation...
For the first time, a powder of refractory body-centered cubic (bcc) HfTaTiNbZr-based high-entropy alloy (RHEA) was prepared by short-term (90 min) high-energy ball milling (HEBM) followed spark plasma sintering (SPS) at 1300 °C for 10 min and resultant bulk material characterized XRD SEM/EDX. The showed ultra-high Vickers hardness (10.7 GPa) density 9.87 ± 0.18 g/cm³ (98.7%). Our found to consist HfZrTiTaNb-based solid solution with bcc structure as main phase, hexagonal closest packed...
Masked stereolithography printing can be used to produce functionalised magneto-responsive polymer structures. Magnetic filler additivation of the photopolymer enables production powerful and fast soft robotics. However, current approaches require high concentrations, reducing mechanical properties compromising processability. In this study, FeNi nanoparticles were added a take advantage their magnetic response magnetisation. Field-assisted gives rise anisotropy by arranging...

Magnetic phase transitions at the Curie temperature are essential for applications like magnetocaloric refrigeration, magnetic sensors, and actuators, but reliance on costly, scarce rare-earth materials limits sustainability. Developing affordable, rare-earth-free with tunable properties scalable miniaturization methods is vital advancing technology. We present a comprehensive synthesis approach compositionally complex alloys (CCAs) transitions, spanning from bulk to nanoparticles....
In our search for an optimum soft magnet with excellent mechanical properties which can be used in applications centered around “electro mobility”, nanocrystalline CoCrFeNiGax (x = 0.5, 1.0) bulk high entropy alloys (HEA) were successfully produced by spark plasma sintering (SPS) at 1073 K of HEA powders energy ball milling (HEBM). SPS non-equiatomic CoCrFeNiGa0.5 particles results the formation a single-phase fcc HEA, while equiatomic CoCrFeNiGa composition mixture bcc and phases was found....
