Ductilematerialit
Ductilematerialit, or ductile materials, are solids that can undergo substantial plastic deformation before fracture. They are typically metals, although some polymers also show ductile behavior under appropriate conditions. Ductility is commonly quantified in a tensile test by the percent elongation at fracture or the reduction of area after break. Materials with high ductility can be drawn into wires or shaped through forming processes without sudden brittle failure.
The microscopic mechanism behind ductility is the movement of dislocations within the crystal lattice, allowing permanent
Common ductile materials include mild and alloy steels, aluminum and its alloys, copper, and nickel-based or
