Question

define ductility..............










​

Answer 1

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.

Answer 2

Explanation:

the ability of a material to have its shape changed (as by being out into wire or thread) without losing strength or breaking When certain alloys are added to metal, hardness and strength can be improved without decreasing the ductility.
