Figure 5

(a) Lattice strain evolutions of {111} and {222} crystallographic planes, (b) stacking fault probability (SFP, 10−3), (c) mean-square strain, (MSS, 〈ε250〉111, 10−6), and (d) stacking fault energy (SFE, mJ/m2) as a function of true strain in AM SS 316 L and AM CrCoNi. Shown a schematic of lattice spacing changes due to an intrinsic stacking fault in inset of Fig. 5a. Included the low strain rate (LSR) of 2 × 10−5 s−1 and the high strain rate (HSR) of 2 × 10−3 s−1 cases.
