Hot works is a processes where metals are plastically deformed above the recrystallization temperature. Below is types of hot works EXCEPT....
Forging
Extrusion
Rolling
Drawing
Cold works is a process of
elastic deformation that occurs below recrystallization temperature
plastic deformation that occur below recrytallization temperature
elastic deformation that occurs above recrystallization temperature
plastic deformation that occur above recrytallization temperature
Advantages of cold works EXCEPT....
No appreciable recovery takes place during deformation
Improve hardness, tensile, fatigue in metal.
Produce good surface finish on metal.
expensive
Extrusion is
a bar or metal is forced from an enclosed cavity via a die orifice by a compressive force applied by a ram.
passing a piece of metal between two rolls
the metal is hammered or pressed into a desired shape.
rod or wire stock is drawn through one or more tapered wire drawing dies
