ductility,

ability of a metal to plastically deform without breaking or fracturing, with the cohesion between the molecules remaining sufficient to hold them together (see adhesion and cohesionadhesion and cohesion,
attractive forces between material bodies. A distinction is usually made between an adhesive force, which acts to hold two separate bodies together (or to stick one body to another) and a cohesive force, which acts to hold together the like or unlike

). Ductility is important in wire drawing and sheet stamping. The metal must neither break nor be scraped off during these processes. Platinum, steel, copper, and tungsten have high ductility. Ductility is a focus of rheology, the study of how materials deform and flow in response to force.

Therefore, the general design practice is to select a steel with an appropriate ductile-brittle transition temperature for the application.
The phenomenology of polymeric fracture is examined, including brittle and ductile failure, and the ductile-brittle transition temperature (DBTT).
Results from the impact tests show that in blends with an IPN structure, the continuous SEBS phase affords the material a high impact resistance, which is maintained at temperatures well below the ductile-brittle transition temperature of PP, and is not markedly affected by the presence of a weld line.
