what is the difference between hardness and toughness
Answers
Answer:
Hardness: A material's ability to withstand friction, essentially abrasion resistance, is known as hardness. ... Toughness: How well the material can resist fracturing when force is applied. Toughness requires strength as well as ductility, which allows a material to deform before fracturing.One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing. It is also defined as a material's resistance to fracture when stressed. Toughness requires a balance of strength and ductility.
