This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.

Two Dimensional Lattice Boltzmann Method for Cavity Flow Simulation
This paper presents a simulation of incompressible viscous flow within a two-dimensional square cavity. The objective is to develop a method originated from Lattice Gas (cellular) Automata (LGA), which utilises discrete lattice as well as discrete time ...

High-energy spin waves in the spin-1 square-lattice antiferromagnet La_{2}NiO_{4}
Inelastic neutron scattering is used to study the magnetic excitations of the S=1 square-lattice antiferromagnet La_{2}NiO_{4}. We find that the spin waves cannot be described by a simple classical (harmonic) Heisenberg model with only nearest-neighbor ...

Cubic Bézier curves are used in the synthesis of novel surface‐based metamaterials with tunable mechanical properties. Surface‐based geometries are 3D printed and tested in compression. The resulting mechanical properties are correlated to changes in the shape of the base curve, with high potential in energy absorption through the adjustment of their ...

Ti‐6Al‐4V samples produced by laser‐powder bed fusion are tested for static and dynamic mechanical properties to systematically evaluate the effects of surface roughness and internal porosity when using productivity parameters. The most detrimental impact to fatigue is caused by surface roughness, lack of fusion and keyhole porosity in descending order.

We investigate the instability toward a double-Q state, which consists of a superposition of two spin density waves at different wave vectors, on a two-dimensional noncentrosymmetric square lattice in an in-plane external magnetic field.

Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

This study compares the mechanical properties of Inconel 718 with two newly developed compositionally complex alloys (CCAs). Inco‐like‐H alloy demonstrates significantly improved wear resistance, surface finish, and hardness, notably at high temperatures. This CCA requires no heat treatment and is well suited for additive manufacturing. Its performance
