Extended Data Fig. 5: Detailed g·b analysis of partial dislocations in the cryogenically (87 K) strained (6%) samples and the calculation of SFE.
From: Dual-scale chemical ordering for cryogenic properties in CoNiV-based alloys
(a) Measured dissociated distances as a function of the angle between the Burgers vector and dislocation line in solid-solution treated and cryogenically strained CoNiV(SS) and CoNiV-AlTi(SS) samples, which indicates that the addition of 2 at.% Al and 2 at.% Ti in our work has no significant influence on SFE. (b) The comparison among CoNiV(SS), CoNiV(SSA) and CoNiV-AlTi samples, revealing the role of ordering on SFE. Despite an increase role of SRO on CoNiV alloys’ SFE, the increment here (~8 mJ/m2) is not significant considering the measurement error (~8.5 mJ/m2). The detailed calculation procedure of SFE was presented in Supplementary Note 2.
