Hardness a fixed height onto a material. This type of hardness is related to elasticity. The device used to take this measurement is known as a scleroscope. Two scales that measures rebound hardness are the Leeb rebound hardness test and Bennett hardness scale. There are five hardening processes: Hall-Petch strengthening, work hardening, solid solution strengthening, precipitation hardening, and martensitic transformation. In solid mechanics, solids generally have three responses to force, depending on the amount of force and the type of material: Strength is a measure of the extent of a material's elastic range, or elastic and plastic ranges together.
