Gradient-structured high-entropy alloy with improved combination of strength and hydrogen embrittlement resistance

Abbas Mohammadi et al.

Summary: High-strength materials often lack resistance to hydrogen embrittlement. In this study, gradient structures with surface nanotwins were introduced in a high-entropy alloy, resulting in materials with both high strength and good ductility under hydrogen. This research is significant for the development of hydrogen-resistant materials.

Microstructure and defect effects on strength and hydrogen embrittlement of high-entropy alloy CrMnFeCoNi processed by high-pressure torsion

Abbas Mohammadi et al.

Summary: In this study, various kinds of defects were introduced into a CrMnFeCoNi Cantor alloy by plastic straining, and the correlations of applied strain, microstructural features, strength, and hydrogen embrittlement were investigated. It was found that introducing twins and defects with low mobility can enhance the yield strength and improve the hydrogen embrittlement resistance of the alloy.

In-situ carbide-reinforced CoCrFeMnNi high-entropy alloy matrix nanocomposites manufactured by selective laser melting: Carbon content effects on microstructure, mechanical properties, and deformation mechanism

Young-Kyun Kim et al.

Summary: The study investigated the effect of carbon content on the microstructure evolution, tensile properties, and deformation mechanisms of high-entropy alloy matrix nanocomposites additively manufactured by selective laser melting. It was found that an increase in carbon content led to enhancements in strength, work hardening rate, and elongation, while also affecting the microstructural features such as nano-sized carbides and average grain sizes. Furthermore, the formation of dislocation networks and deformation twins were observed, contributing to the high back stresses and yield strengths of the samples.

Hydrogen-enhanced densified twinning (HEDT) in a twinning-induced plasticity (TWIP) steel

Cheng Zhang et al.

Summary: The presence of hydrogen was found to decrease twin thickness and increase twin density in TWIP austenitic steel, influencing its hydrogen embrittlement behavior. This phenomenon, termed hydrogen-enhanced densified twinning, plays an important role in the twinning process of TWIP austenitic steel.

Selective laser melted CrMnFeCoNi+3 wt% Y2O3 high-entropy alloy matrix nanocomposite: Fabrication, microstructure and nanoindentation properties

Young-Kyun Kim et al.

Summary: The Y2O3-reinforced equiatomic CrMnFeCoNi high-entropy alloy (HEA) matrix nanocomposite, fabricated through high-energy attrition milling and selective laser melting (SLM) additive manufacturing, exhibited superior mechanical properties with higher nanohardness compared to similar HEAs produced by casting and SLM. This suggests that dispersion hardening by Y2O3 nanoparticles can effectively improve the mechanical properties of SLM-built CrMnFeCoNi HEA matrix nanocomposites.

Improving the hydrogen embrittlement resistance of a selective laser melted high-entropy alloy via modifying the cellular structures

Zhenghong Fu et al.

Summary: This study demonstrates that modifying cellular structures through controlled annealing can effectively improve the hydrogen embrittlement resistance of selective laser melting processed alloys. Annealing preserved cellular structures while reducing dislocation densities, slightly reducing strength but significantly increasing ductility and HE resistance. The delayed crack initiation and propagation were attributed to hydrogen-enhanced local plasticity with formation of nano-twins and dislocation cells in the modified structures.
