Metals
Crystalline structures made up of grains
Large/Coarse Grains
Formed through slow cooling. Increases tensile strength, toughness, ductility, and malleability
Small Grains
Formed through fast cooling. Decreases tensile strength, toughness, and ductility. Increases brittleness
Alloys
The mixture of a metal with another material.
Alloying
Process of combing a metal with another material. Increases hardness and strength, but decreases malleability and ductility
Work Hardening
Process of increasing the hardness of a metal through applying a process when the metal is cold
Tempering
Application of heat after work hardening. Reduces some of the hardness and stiffness, but it increases the toughness and ductility of the metal
Super Alloys
Metal alloys that exhibit high degrees of mechanical strength, resistance to corrosion, and surface stability
Creep
Slow expansion or deformation of a material over time. Can be exaggerated by high temperatures or prolonged force
Oxidation
The reaction of metal with oxygen
Ferrous Alloys
Alloys containing iron, making them magnetic. Mild steel, stainless steel, and cast iron
Non-ferrous alloys
Alloys that do not contain iron. Aluminum, copper, silver, tin, and zinc
Galvanizing
Protective coatings that protect against corrosion
