Web12.4.2.3 Face-centered cubic metals: stacking fault energy. SFE is a very important parameter for FCC metals and primarily governs their deformation behavior. FCC … Stacking faults are two dimensional planar defects that can occur in crystalline materials. They can be formed during crystal growth, during plastic deformation as partial dislocations move as a result of dissociation of a perfect dislocation, or by condensation of point defects during high-rate plastic deformation. The start and finish of a stacking fault are marked by partial line dislocations such as a partial edge dislocation. Line dislocations tend to occur on the closest packed plane i…
