Question

13. Define (a) malleability, and (b) ductility. ​

Answer 1

Answer:

Malleability

Malleability is a substance's ability to deform under pressure (compressive stress). If malleable, a material may be flattened into thin sheets by hammering or rolling. Malleable materials can be flattened into metal leaf. ... It is the ability of a solid to bend or be hammered into other shapes without breaking.

Ductility

Ductility is the ability of a material to be drawn or plastically deformed without fracture. It is therefore an indication of how 'soft' or malleable the material is. The ductility of steels varies depending on the types and levels of alloying elements present.
