Abstract Shear bands dictate the failure mechanisms of alloys across various strain rates and limits damage tolerance alloy. While localized amorphization has potential to mitigate shear effects, it thus far been confined nanoscale. Here, we extend micrometer scale, fundamentally replacing shear-dominated in multi-principal element alloy micropillars. Instead applying a single rate, implement continuous compression training from low high rates, generating top-down high-density dislocation gradient that drives formation topological lattice disorder network, extending over one-third micropillar height (hyper-range amorphization). Within amorphous bands, atoms exhibit dynamic disorder, rearranges recovers dissipating stress. The achieves an ultimate compressive strength ceramic level (~6.5 GPa), while maintaining ~59.1% plasticity. This work reveals engineering-based mechanical mechanism for amorphization, establishing as viable pathway enhancing structural stability energy dissipation capacity alloys.

Metal–organic assemblies (MOAs), with multiple active sites and well-defined lithium transport pathways, are considered ideal electrode materials for lithium-ion batteries. However, their further development is impeded by poor structural stability limited electronic conductivity. In this study, two isostructural one-dimensional MOAs, namely, [M(pyzdc)(H2O)2]n (M-1D, M = Co Ni; H2pyzdc pyrazine-2,3-dicarboxylic acid) were synthesized storage. The chain structure formed hydrogen bond interactions constitutes a three-dimensional supramolecular architecture. This unique network not only enhances but also facilitates efficient electron transfer. When tested as anode materials, Co-1D Ni-1D exhibited reversible capacities of 1003.3 841.3 mAh g–1 at 100 mA after cycles, respectively. Theoretical calculations kinetic analyses have elucidated the impact configuration on adsorption diffusion in these highlighting intricate relationship between MOAs storage behavior.
