Scientists create metal alloy that absorbs hydrogen under extreme pressure
Researchers have synthesized a new high-entropy alloy that can absorb hydrogen at extreme temperatures and pressures, expanding the potential uses of high-entropy materials in energy storage and industrial applications. The discovery demonstrates that these complex multi-element alloys are more chemically versatile than previously understood, with implications for next-generation materials in aerospace, energy, and manufacturing sectors.
Originaltitel: Synthesis of high-entropy hydride from the cantor alloy (fcc–CoCrFeNiMn) at extreme conditions
Studies of high-entropy materials contribute to various fields of science and reveal ever more exciting properties of applied interest. Here, we perform a study of the resistance of a Cantor alloy (CoCrFeNiMn) to hydrogen through high-pressure experiments at elevated temperatures by X-ray and neutron time-of-flight experiments and ab initio calculations. We report formation of an fcc hydride based on the Cantor alloy composition. We also provide its characterization, including an estimate of hydrogen content. These findings contribute to the growing body of knowledge on the complex chemistry of high-entropy alloys and high-entropy hydrides.
