摘要：A multi-scale in-situ visual quantitative analysis system has been developed to enable real-time, monitoring breathing behaviors of metal hydrides reactor (MHR). The system enables observation of metal hydride expansion, pulverization, and motion, while establishing correlations between crack evolution during hydriding/dehydriding and both strain accumulation and regional reaction behavior. The results indicate that strain accumulation and regional variations in hydriding rates are strongly correlated with crack evolution, which originates from particle rearrangement. The transition of MH particles from a homogeneous, loosely packed state to a heterogeneous, compacted structure can be evidenced by the dynamic breathing behavior of cracks. Dynamic intervention and dispersion effects effectively regulate the spatial distribution of particles, reset strain accumulation patterns, and enhance region mass transfer behavior. Compared with conventional reactors, the strain at the fifth cycle is significantly reduced from 9.85 mε to 1.41 mε, corresponding to a decrease of 85.7%. The hydriding rates in the upper, middle, and lower reactor wall regions increase by 16.7%, 2.9%, and 43.4%, respectively, resulting in an overall improvement of 21% (at a reaction fraction of 0.9).
