The Viability of the Refractory High‐Entropy Alloy AlMo0.5NbTa0.5TiZr for High‐Temperature Structural Applications

Advanced Engineering Materials, EarlyView.
Refractory high‐entropy alloys have attracted substantial attention for future ultrahigh‐temperature structural applications. Here the progression of key phase transformations in AlMo0.5NbTa0.5TiZr is established and correlated to the mechanical performance, highlighting the importance of the B2 phase.

Inoculating solid-state homogeneous precipitation by impurity atoms through a spinodal decomposition like pathway [PDF]

arXiv
Solid-state homogeneous precipitation of nano-sized precipitates is one of the most effective processes to strengthen metal alloys, where the final density and size distribution of precipitates are largely controlled by the precipitation kinetics. Here, we report a strategy to inoculate the homogeneous precipitation of coherent precipitates to enhance ...

Influence of a Hydrogen Addition to the Inert Gas and Subsequent Heat Treatments on the Microstructure and Mechanical Properties of Magnesium WE43 Fabricated by PBF‐LB/M

Advanced Engineering Materials, EarlyView.
This article investigates optimal processing conditions for the laser‐based powder bed fusion of WE43. To limit the interaction with remaining oxygen, a 3 vol% hydrogen admixture to the inert gas is investigated. Furthermore, heat treatments are investigated in the range of 250–350 °C for 48 h.

Exploring the Effect of Polymer Addition to the Room Temperature Synthesis of Colloidal Lead Halide Perovskite for Better Stability, Higher Passivation, and More Uniform Particle Size

Advanced Engineering Materials, EarlyView.
This study examines the incorporation of the polymer BUTVAR during the synthesis of various perovskite structures at room temperature The study demonstrates that the incorporation of the polymer solution enhances the optical characteristics and improves the shape uniformity of the resultant perovskite material without altering the inherent structure of

High‐Entropy Ti, Zr, Hf, Ta Multiphase Diboride with Deformation Resistance up to 2000 °C

Advanced Engineering Materials, EarlyView.
Ceramics are brittle and strength decreases with temperature. The multiphase high‐entropy (Ti0.25Ta0.25Hf0.25Zr0.25)B2 with heterogeneity at the nano‐ and microscale demonstrates deformation resistance up to 2000 °C, with maximum bending strength at 1800 °C.
