slipsystem
Slip system refers to a specific combination of a crystallographic plane and a crystallographic direction along which dislocations move during plastic deformation. A crystal can deform plastically when dislocations glide along active slip systems under applied stress. The likelihood that a given system will conduct plastic flow depends on the resolved shear stress on that system, which is determined by the orientation of the applied load relative to the slip plane and slip direction (often described by the Schmid factor).
Materials with numerous close-packed slip systems tend to be more ductile because many dislocation glide paths
Common examples: In face-centered cubic (FCC) metals such as aluminum and copper, the primary slip systems are
Understanding slip systems helps explain material strength, ductility, and formability and underpins processes such as forging,
