Study Notes
Metal Properties
- The property of metals that refers to resistance to penetration by other materials is hardness.
- The property that allows a metal to be bent, rolled, or changed in shape without breaking is ductility.
Hardenability
- Copper exhibits poor hardenability, leading to hardening only on the surface.
Heat Treatment
- The process that can increase or decrease the hardness of a metal by treating it differently is heat treatment.
Metal Characteristics
- Steel is much harder than lead or pure aluminum.
Strength and Deformation
- The characteristic of a metal that is defined as the resistance to deformation is strength.
Tempering
- The metal property that is enhanced by the special heat treatment known as tempering is hardness.
Ferrous Metals
- The term 'ferrous' refers to metals that contain iron in the context of metals.
Fluidity
- The property of metals that enables them to join easily with another liquid metal when in a liquid state is fluidity.
Fatigue
- The characteristic that causes a metal to fracture under a repeated load well below its tensile strength is fatigue.
