a Light microscopy image and COMSOL simulation showing the deformed-to-fracture 304L specimen and the distribution of the effective plastic strain (EPS). The scale bar is 2 mm in length. b Regressed RCT values are plotted along with the EPS acquired from COMSOL simulation. Error bars were calculated from three repeated experiments. c EPS distribution mapping and (d) a 0.7 mm × 0.7 mm matrix of microdroplets at the region of necking. e Matrix plot of |Z |1Hz that agrees with the simulated strain distribution. Each pixel represents |Z |1Hz acquired from each droplet, as shown in (d). A 20 mM LiCl + 5% HNO3 solution was used in the impedance scans. Scale bars in (c) and (d) are 0.7 mm in length.
