Summary: In this study, high pressure solidification was successfully used to obtain a metastable Y0.7Zr0.24Ti0.06Fe2 alloy with supersaturated Ti in the YFe2 based C15 Laves phase. The segregation of Ti, Y, Zr and multi-phase formation were suppressed, and the resulting HPS alloy consisted of primary C15 phase (C15-1) and secondary C15 phase (C15-2) with 77.1% and 22.9% of the total content, respectively. Additionally, the hydrogen absorption and desorption capacities were substantially increased. This study demonstrates that the combination of high-pressure solidification and alloying is an effective method for exploring new hydrogen storage materials with metastable structure and high performance.

Summary: In this study, three series of alloys were prepared and their crystal structural characteristics and hydrogen storage properties were investigated. The results showed that a single C14-Laves phase with homogeneous element distribution existed in all alloys. The hydrogen absorption/desorption plateau of the alloys increased as the Fe, Mn, or Ti content increased. The hydrogen storage capacity of the alloys also correlated negatively with the hydrogen affinity of interstitial sites. Ti0.935Zr0.085Cr1.3Mn0.3Fe0.4 alloy exhibited saturated hydrogenation under 8 MPa at 293 K and dehydrogenation around 24.91 MPa pressure at 363 K with a hydrogen capacity of 1.74 wt%, as well as excellent cycling performance and mere hysteresis. Ti0.92Zr0.10Cr1.0Mn0.6Fe0.4 alloy showed promising hydrogen capacity of 1.86 wt% at 283 K and a dehydrogenation pressure of 27.94 MPa at 363 K, along with satisfactory cycling durability. This study can guide the compositional design of AB2-type hydrogen storage alloys for hydrogen compression application.

Summary: To replace mechanical compressors in hydrogen infrastructures, new compositions are needed to achieve a pressure of 700 bar. This study synthesized and characterized Ti1.1(Cr,Mn,V)2 and Ti1.1(Cr,Mn,V,Fe)2 compositions based on Laves (C14) intermetallic compounds, which show increased plateau pressure and hysteresis gap due to the substitution of Cr with Mn and Fe. These alloys have suitable thermodynamics for high-pressure hydrogen compression, easy activation at room temperature, and fast reaction rates. The most promising composition, Ti1.1Cr0.9Mn0.8V0.1Fe0.2, is estimated to release hydrogen at 700 bar and 150 degrees C. The integration of these alloys in a metal hydride compressor is evaluated.

Summary: The Ti-Zr-Cr-Fe-V alloys with different compositions exhibit good hydrogen storage properties at moderate working temperatures. Increasing the V content is beneficial for activation kinetics and higher hydrogen storage capacity, but it reduces plateau pressure and increases plateau slope factor. The Zr and Fe content in the alloys also significantly affect hydrogen storage properties.

Summary: Fractured C14 (hexagonal close-packed) Laves phase Zr(Fe,Cr)2 precipitates were observed in beta forged Zircaloy4. The fractures mainly occurred along the c-axes of Laves phase precipitates. The narrow interfacial width and small misorientation angle suggested the retention of brittle nature at high temperature.

Summary: Heusler compounds with Fe2V1-xTaxAl1-ySiy composition have shown high thermoelectric power factors due to band convergence and band gap opening by V/Ta substitution. Investigation on solubility limits of Ta and Si within the L21 phase revealed significant hindrance by Al/Si substitution. Different annealing conditions affect microstructure and thermoelectric properties, with additional annealing leading to phase segregation and impurity precipitate growth, impacting Seebeck coefficient and thermal conductivity.

Summary: Hydrides of the AB(2) Laves type alloys show efficient hydrogen storage capabilities and are suitable for designing high-performance hydrogen storage devices operating at ambient conditions. Experimental results indicate that the hydrogen absorption and desorption processes are jointly influenced by hydrogen diffusion and grain boundary nucleation, with increasing hydrogen content in the hydride leading to lower activation energies.

Summary: Heterogeneous crystalline-amorphous nanostructures exhibit superior strength-ductility synergy through the cooperative effects of nanograins and amorphous grain boundaries in co-deformation. In this study, a facile laser surface remelting technique was successfully developed to fabricate a 100 μm-thick gradient nanostructured layer with phase decomposition on a TiZrHfTaNb0.2 high-entropy alloy. A 5 μm-thick crystalline-amorphous nanostructured surface layer with an average grain size of 7 nm was obtained. This nanostructured layer demonstrated an ultrahigh yield strength of 6.0 GPa and a compression strain of 25% during localized micro-pillar compression tests. Co-deformation cooperative mechanisms observed included well-retained dislocation activities in nanograins and crystallization in amorphous grain boundaries, resulting in grain coarsening through grain boundary-mediated plasticity. This study provides insights into the development of high-performance high-entropy alloys with novel crystalline-amorphous nanostructures and their plastic deformation mechanisms.
