Ductility is a mechanical property used to describe the extent to which materials can be deformed plastically In materials science, deformation is a change in the shape or size of an object due to an applied force. This can be a result of tensile forces, compressive (pushing) forces, shear, bending or torsion (twisting). Deformation is often described as strain without fracture The word fracture is often applied to bones of living creatures, or to crystals or crystalline materials, such as gemstones or metal. Sometimes, in crystalline materials, individual crystals fracture without the body actually separating into two or more pieces. Depending on the substance which is fractured, a fracture reduces strength or inhibits.
In materials science Materials science or materials engineering is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. This science investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It includes elements of applied, ductility specifically refers to a 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 concept, refers to 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. Ductility and malleability do not always correlate with each other; for instance, gold is both ductile and malleable, but lead is only malleable.[1] Commonly, the term "ductility" is used to refer to both concepts, as they are very similar.
