Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material.
Annealing is achieved with heat treatment processes that require a neutral (or inert) controlled atmosphere.
Brazing allow diverse configurations of parts, dissimilar metals and non-metals of non-uniform thickness to be joined.
A carburizing atmosphere must be able to transfer carbon (also nitrogen in the case of carbontriding) to steel surface.
Neutral hardening is a heat treatment procedure for steels with the aim to produce a martensitic microstructure.
The process of fusing and applying alloys to alloys to the joint between metal objects as to unite them without heating the objects to the melting point.
