Crystalline slip system
A crystalline slip system consists of a specific slip plane and slip direction along which dislocations move during deformation. The number of these systems affects the metal's formability.
Physicochemical Mechanism of Action
A crystalline slip system consists of a specific slip plane and a slip direction, along which dislocations of atoms or ions occur during plastic deformation. These systems enable the movement of atomic rows within the crystal, leading to strain and deformation.
Metallurgical Relevance & Welding Risks
The number and type of active slip systems influence the formability of a metal. Too few systems can result in high resistance to deformation, leading to fractures or splintering during processing. Conversely, too many active systems can make the material too soft and compromise its mechanical properties.
Workshop Practice & Instructions
In welding, it is important to adjust temperature and time so that the metal is welded in its optimal formability. This can be achieved by choosing the appropriate welding process and correct process parameters. For steels with many active slip systems, slow cooling is required to stabilize the structure and avoid cracking.
