The process of heat treatment includes things such as controlled heating and cooling metals with the aim of altering their mechanical and physical qualities without changing their shapes. In some cases, this process is undertaken inadvertently due to the manufacturing method which either heat up or cool the metal such as welding or forming. We share details of heat treatment solutions below so as to grow your knowledge in this field.
Another method of heating steel is annealing and it keeps it to a particular temperature by cooling down at a suitable rate. This increases features such as the machinability, softness and cold working attributes of the steel and even helps in removing the stresses of the material and thus it obtains the right structure. In full annealing, the material is heating to a temp where the carbide turns into a solution completely or in part and then is cooled down. Sub critical annealing takes place at a temperature that is a bit lower than the temperature where the carbide starts tuning into a solution.
The process of ageing is one that leads to structural changes. This usually takes place in definite metals and alloys at high temperatures or atmospheric temperature. As a result of ageing, hardness values, ageing, and maximum increase while the ductility lowers. There are particular conditions in which ageing is achieved through heating at an elevated temperature. This is usually referred to as artificial ageing and its result is precipitation hardening.
Carburizing is a process that involves introducing carbon into the surface layer of the steel which does not have a high carbon content. It might be achieved by heating it in a solid, gaseous or liquid medium which includes carbon. When done at elevated temperatures, it provides a … Read More..Read More →
