| Hardening | the strengthening of a metal by plastic deformation |
| Steel | an alloy of iron and a small amount of carbon |
| Toughness | the ability of a material to absorb energy and plastically deform without fracturing |
| Phase Diagrams | a type of chart used to show conditions at which thermodynamically distinct phases can occur at equilibrium |
| Metallic Bonding | the attraction of many metal atoms together, which creates a sea of free floating electrons |
| Stress | the internal resistance, or counterforce, of a material to the distorting effects of a load or force |
| Cold-Working | a type of metal working done by subjecting a metal with enough force to cause plastic deformation |
| Heat Treating | involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material |
| Conductivity | the the abilty to transfer electrons or heat |
| Fatigue | the progressive and localized structural damage that occurs when a material is subjected to cyclic loading |
| Failure | the result of metal fatigue |
| Strength | a measure of how well a material can resist being deformed from its original shape. |
| Quenched | the rapid cooling of a workpiece to obtain certain material properties. |
| Annealing | a heat treatment that alters a material to increase its ductility and to make it more workable. |
| Drawn | a metalworking process which uses tensile forces to stretch metal |
