What are the Implications of Grain Boundary Sliding for Material Properties?
The implications of GBS on material properties are profound:
- Mechanical Strength: GBS can lead to a decrease in mechanical strength as grains slide past each other under stress. This is a critical consideration in designing nanomaterials for structural applications. - Ductility: GBS can enhance ductility by allowing grains to accommodate plastic deformation without fracturing. - Creep Resistance: In high-temperature applications, GBS can contribute to creep, a time-dependent plastic deformation. Understanding and controlling GBS is essential for improving creep resistance in nanomaterials.
