  1. Axial strain and differential stress represent the final experimental values. Differential stress_0.10 represents the stress value at an axial strain of 0.10. In Sample B, the hardening coefficient is not available due to damage to the copper holder (see Supplementary Text 1 and Supplementary Fig. 2 for details).
