WebMay 1, 2015 · The coherent twin shows effectively no VDZ, as is highlighted in Fig. 5 (a), while the incoherent twin, shown in Fig. 5 (b), indicates an average VDZ of 129 nm. The large difference in VDZ between the {111} and {112} symmetric tilt GB planes follows the same trend as the Cr RIS measurements. WebApr 20, 2024 · Our results suggested this ITGB as a mirror-glide boundary formed by gliding the atoms along [20 2 ¯ 1 ¯] of a {10 1 ¯ 4}< 20 2 ¯ 1 ¯ > coherent twin boundary due to its interaction with stacking faults. The ITGB can be further stabilized by partial-column Gd substitution, leading to the observed unique segregation pattern. orcas island electrician
