The normalized concentration as a function of degrading time at 25 °C (a) for BM G-Fe powder¹⁹, G-FeSiB ribbon²¹, S1 and BM G-MgZn¹⁹, and (b) for S3, S2 and S1. The solid lines are fitting curves by an exponential decay function. (c) Comparison of the reaction efficiency among different powders. Here, the concentration of all the DB6 solutions is 0.2 g/L while the dosage is different for different agents, i.e., 0.01 g/mL for HEAs powders, 0.0133 g/mL for G-FeSiB, 0.0134 g/mL for G-Fe, and 0.006 g/mL for G-MgZn.
