Question

Differentiate between malleable and ductile substances.​

Answer 1

ANSWER

• Ductility and malleability are two aspects of the plastic deformation process of solid materials. Since metals have a crystal structure and free electrons to allow large amounts of dislocations, they are both highly malleable and ductile.

• Ductility of a solid material is the ability to undergo tensile stress without fracture or damage; simply the ability to draw a material into a wire by pulling at the ends

• Malleability of a material is the ability to undergo compressive stress without fracture or damage; simply, it is the ability to be hammered or pushed into thin sheets without breaking.

• In most cases, ductility and malleability are coexisting. Silver and gold are highly malleable and ductile. But in some cases ductility can be higher while malleability is low or vice versa. For example, Lead and cast iron are highly malleable while having lower ductility.

Ductility is said to be the property of a material to stretch without getting damaged. Metals having ductile property can be stretched into wires. ... Malleability is said to be the property of a material to deform under compression. The metals having malleable property can be rolled or beaten into sheets.
