Ductility

Ductility is the ability of a material to sustain significant plastic deformation before fracture when undergoing tension, i. e. when the relevant elastic modulus is Young's; the equivalent for deforming under bulk compression, i.

e.
when using the bulk modulus, is malleability.
Historically, materials were considered malleable if they were amenable to forming by hammering or rolling.
