An Overview of Heat Treatment Solutions

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. Below are some heat treatment solutions so as to grow your knowledge.

Another method of heating steel is annealing and it keeps it to a particular temperature by cooling down at a suitable rate. This enhances the softness, machinability and cold working features of the steel and even aids in eliminating the stresses of the material thus it gets the desired structure. The material is heating up to a specific temperature in full annealing and thus the carbide turns into solution either fully or partially and then it 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 procedure of ageing results in structural changes. Typically, this happens in specific metals and alloys at atmospheric temperature or temperatures which are high. Because of ageing, proof stress, hardness values and maximum stress go up as the ductility reduces. There are specific conditions where ageing is achieved through heating at a high temperature. This is usually referred to as artificial ageing and its result is precipitation hardening.

Carburizing is a method in which carbon is introduced into the surface layer of the steel whose carbon content is low. It could be effected by heating it inside a liquid, gaseous or solid medium that has carbon. When carried out at high temperatures, it gives a carbon supply which will be absorbed by the carburized substance. The concentration of the carbon and the depth in its steel surfaces is varied by controlling the temperature and the time which the heat treatment requires.

Hardening is a process which enhances the hardness of the material using heat treat. Normally, this implies heating to a temperature which is more than the critical range by maintaining the temperature at a range where diffusion will be achieved by quenching in air, oil or water.

In the induction hardening procedure, the steel is hardened through heat treat. It is undertaken by alternating a magnetic field to that of a higher temperature or that which is close to the range of transformation and then quenching follows.

Normalizing is an approach used in used treatment which necessitates heating to and when required even keeping the same at a temperature which is then followed by cooling down the still air. This allows the cooling to occur quickly at a medium level.
