Heat treatment
salt baths
Metals; Heat treatment
A method of providing thermal processing of steels using a bath of molten salts. The process prevents oxidation and provides a very uniform heating environment for hardening and tempering.
hot iso static processing (HIPping)
Metals; Heat treatment
This process is used for the densification of castings and pre-sintered components, as well as in the diffusion bonding of alloys. The process usually uses very high temperatures and pressures within ...
sintering
Metals; Heat treatment
Treatments which strengthen the molecular bonding of powder compacted components. Many products with complex cross sectional forms are manufactured from powdered, core material, which is pressed or ...
homogenizing
Metals; Heat treatment
Holding at a high temperature to eliminate or decrease chemical segregation by diffusion.
decarburization
Metals; Heat treatment
Loss of carbon from the surface layer of a carbon-containing alloy when the metal is subjected to high temperatures. The loss of carbon at the surface reduces the strength of the part.
cold treating
Metals; Heat treatment
Often referred to as Cryogenic Treatment, or Deep Cryogenic Treatment, this process occurs after quenching with the intention of converting retained austenite into martensite, and is achieved by ...
hardenability
Metals; Heat treatment
Refers to the ability of steel to harden deeply upon quenching, based on the size of the part and the method of quenching being used. The Jominy Test is used to determine the hardenability of ...
