“…These two processes are interconnected as the fines produced during the absorptiondesorption cycles tend to percolate to the lowest areas increasing the packing ratio and the tensions produced [13]. Some studies show that tension keeps building up even after plastic deformation of the containment vessel [14], while other studies report higher tension values during activation of the hydride [15,16]. Changes in alloy powder itself have been reported due to tension accumulation, reducing particle size and compacting the powder [17,18].…”
