Extended Data Fig. 3: Mechanical characterization of NiSiCrFeB(O) metallic-glass nanotubes.
From: Oxidation-induced superelasticity in metallic glass nanotubes
a. A nominal stress-strain curve of the NiSiCrFeB(O) metallic-glass nanotube under in-situ micro-compression subject to the strain rate of 0.06 S−1 and the maximum strain of 15.4%, b. The SEM images of the corresponding NiSiCrFeB(O) metallic-glass nanotube before and after microcompression, c. Effect of the maximum strain on the recoverable strain at the strain rate of 0.06 S−1 or 0.003 S−1. Note that the recoverable strains measured from image correlations were repeated five times for averaging and data are presented as mean values +/−SD. d. Comparison of the load-depth data obtained from the indenter tip displacement and image correlation.
