explain Malleablity and Ductility
Answers
Answer:
Malleability is the ability of a material to deform under stess (compressive stress). If a material is malleable then it can be converted into thin sheets by hammering or rolling. Ductility of a material is the ability to stretch under stress (tensile stress). ... Generally many metals have high malleability and ductility.

*Ductility is a measure of a material's ability to undergo significant plastic deformation before rupture or breaking, which may be expressed as percent elongation or percent area reduction from a tensile test. According to Shigley's Mechanical Engineering Design significant denotes about 5.0 percent elongation.
*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. ... Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead.
