AB - Interstitial metal hydride alloys exhibit significant volume changes between the hydrogenated and dehydrogenated states during cycling, resulting in macroscopic stresses in powder beds that must be considered in tank design. Interactions are complex, and these stresses are primarily influenced by the local particle size distribution (PSD) and packing density. This study examines radial expansion forces in vertical storage containers using AB 2 - type hydride alloys and synchrotron-radiation micro-computed tomography (SRμCT). Up to 50 cycles, progressive particle decrepitation occurs, with densification in the lower layers reaching a 91 LB - PUB:(DE-HGF)16 DO - DOI:10.1016/j.ijhydene.2026.153776 UR - https://bib-pubdb1.desy.de/record/646216 ER -
