Definitions for ductility
This page provides all possible meanings and translations of the word ductility
the malleability of something that can be drawn into threads or wires or hammered into thin sheets
Ability of a material to be drawn out longitudinally to a reduced section without fracture under the action of a tensile force.
the property of a metal which allows it to be drawn into wires or filaments
Origin: [Cf. F. ductilit.]
In materials science, ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into a wire. Malleability, a similar property, is a material's ability to deform under compressive stress; this is often characterized by the material's ability to form a thin sheet by hammering or rolling. Both of these mechanical properties are aspects of plasticity, the extent to which a solid material can be plastically deformed without fracture. Also, these material properties are dependent on temperature and pressure. Ductility and malleability are not always coextensive – for instance, while gold is both ductile and malleable, lead is only malleable. The word ductility is sometimes used to embrace both types of plasticity.
