(a) Tensile stress-strain curves for 35.26° samples with TB spacing 2.5–25.0 nm. (b) Initial yield strain, strain at the end of TB migration and strain at peak stress versus TB spacing. (c) Initial yield stress, peak stress and average flow stress during TB migration versus TB spacing. (d) Strain hardening factor k = σ m /σ y versus TB spacing. σ m and σ y denote the peak stress and the initial yield stress, respectively.
