Stacking Fault Tetrahedron - an overview | ScienceDirect Topics
SFTs are identified by their triangular images in weak-beam or two-beam conditions when observed from <110> direction. An example is shown in Fig. 7.6. SFTs can form in austenitic …
Molecular dynamics studies on formation of stacking fault tetrahedra …
2021年1月1日 — We study the formation of SFT based on the Silcox-Hirsch mechanism by collapsing the triangular plate of vacancies to Frank loop in case of low stacking fault energy …
Stacking fault tetrahedra in metals - ScienceDirect
2015年1月1日 — Stacking fault tetrahedra (SFT) were first observed in samples of quenched gold, by Silcox and Hirsch in 1959 [1]. They suggested that the tetrahedra were formed by the …
The role of stacking fault tetrahedra on void swelling in …
2024年4月16日 — Here, by combining atomistic simulations and STEM imaging, we find stacking fault tetrahedra (SFTs) are the primary cause of the high swelling rate in pure fcc copper. We …
Atomic-scale dynamic process of deformation-induced stacking fault ...
2013年8月15日 — Stacking fault tetrahedra, the three-dimensional crystalline defects bounded by stacking faults and stair-rod dislocations, are often observed in quenched or irradiated face …
Mobility and coalescence of stacking fault tetrahedra in Cu
2015年3月13日 — Stacking fault tetrahedra (SFTs) are ubiquitous defects in face-centered cubic metals. They are produced during cold work plastic deformation, quenching experiments or …
Stacking-fault tetrahedra in annealed f.c.c. metals and alloys
Analyses of partially formed stacking-fault tetrahedra and intrinsic fault bends suggest that the tetrahedra arise from the annealing of intersecting faults in the newly recrystallized grains by a …
Closed and open-ended stacking fault tetrahedra formation along …
Stacking fault tetrahedra (SFTs) are volume defects that typically form by the clustering of vacancies in face-centred cubic (FCC) metals. Here, we report a dislocation-based …
Direct transformation of equilateral hexagonal Frank vacancy …
2022年7月22日 — Stacking fault tetrahedra (SFTs) are highly interesting three-dimensional vacancy defects in quenched, plastically deformed or irradiated face-centered-cubic metals …
Story of stacking fault tetrahedra - ScienceDirect
1997年9月1日 — Stacking fault tetrahedra, although they have a peculiar structure, are the most general type of vacancy clustered defects in f.c.c. metals and alloys. Placing these stacking …
