Fig. 6: Mechanical properties of the quinary o-MAXs.
a Typical stress-strain curves of the three o-MAXs under a compressive rate of 10−3 s−1. b The elastic modulus E (in green), nanoindentation hardness H (in blue), and the calculated E2/H (in red) of the three MAXs with a peak load of 5 mN. c Change on the compressive strength (in dark blue) and E (in green) of the three MAXs upon their chemical composition. d–f High-magnification SEM images show the typical surface morphology after compression tests: Mo1Cr2 (d), Mo1Cr1 (e), and Mo2Cr1 (f), respectively. The yellow arrows indicate the kinking within the grains. The error bars in (b) represent the standard deviations from ten parallel measurements, while the error bars of compressive strength in (c) represent the standard deviations from five parallel measurements.
