Ductility - Wikipedia, the free encyclopedia
|
|
Ductility is a mechanical property used to describe the extent to which materials can be deformed plastically without fracture. In materials science, ductility specifically refers to a material's abi...

The lack of ductility is often termed brittleness. Usually, if two materials have the same strength and hardness, the one that has the higher ductility is more desirable. The ductility of many metals can change if conditions are altered.

The mechanical shaping of metals involves some force impinging on the surface of the metal. (Force/area = stress). For example, to flatten a spherical piece of copper one would deal hammer blows to the top of the sphere. ... Edge dislocations allow slip to occur and slip provides ductility in metals.
