Ductility is the ability of a metal to stretch or elongate before fracture.

Ductility is the ability of a metal to stretch or elongate before fracture.

• A. Be Indented
• B. Be Forged
• C. Stretch Or Elongate
• D. None Of The Above

Answer: (C)

Ductility describes how much a metal can be deformed plastically by stretching or elongating before it finally fractures. That is exactly what the option “stretch or elongate” communicates. Indentation tests relate to hardness, not ductility. Forging is a shaping process that may involve ductile behavior, but it isn’t the definition of ductility itself. None of the above isn’t needed because the concept of stretching or elongating before fracture is precisely what ductility means. In practice, ductility is measured as percent elongation in a tensile test, with ductile metals showing significant elongation and brittle metals failing with little to no deformation.
