Difference between Hardness & Toughness
The key difference between hardness and toughness is that these two properties of materials have an inverse relationship. For a particular solid material; as hardness increases, toughness decreases. Hardness is a measure of a material’s resistance to permanent deformation. Toughness is a measure of how much deformation a solid material can undergo before fracturing.
