Malleability and ductility are related. A malleable product is one in i beg your pardon a thin sheet can be easily formed by hammering or rolling. In other words, the material has the capacity to deform under compressive stress.

You are watching: If a material is ductile it is most likely a


A malleable material is one in which a thin sheet deserve to be quickly formed by hammering. Gold is the most malleable metal.

In contrast, ductility is the capability of a solid product to deform under tensile stress. Practically, a ductile product is a product that can conveniently be stretched right into a wire once pulled as presented in the number below. Recall pulling is using tensile stress.


If we pull on a rod of material, several of the possible profiles the the rods in ~ fracture are shown in the figure below.


Profile (a) is an example of the material that fractures v no plastic deformation, i.e., it is a brittle material. File (b) is an example of a material that fractures after very tiny plastic deformation. These two profiles would certainly be share as having actually low ductility. File (c) in contrast is a product that plastically deforms prior to fracture. This material has high ductility. The stress-strain curves for the brittle, profile (a), and also the ductile material, file (c), are displayed in the figure below.
