Ductility
Ductility
Ductility (/dʌkˈtɪlɪti/), from the Latin ductilis meaning "that can be led", is a term used in materials science to describe a material's ability to deform under tensile stress. This is often characterized by the material's ability to be stretched into a wire.
Etymology
The term ductility originated from the Latin word ductilis, which means "that can be led". It was first used in the context of metals in the 14th century.
Description
In materials science, ductility is a mechanical property that describes the degree to which a material can sustain plastic deformation under tensile stress before failure. Ductile materials can be stretched without breaking and are often used in structures that need to withstand high stress. Examples of ductile materials include copper, aluminum, and steel.
Related Terms
- Malleability: This is another property of metals, which describes a material's ability to deform under compressive stress. It is often compared and contrasted with ductility.
- Brittleness: This is the opposite of ductility. Brittle materials break or shatter under stress instead of deforming.
- Plasticity: This is the general property of all materials to deform irreversibly without breaking or shattering.
- Tensile strength: This is the maximum amount of tensile (pulling) stress that a material can withstand without breaking.
