Overview of The Heat Treatment
Metal treatment is a necessary process that is meant to alter the physical and chemical properties of the metal. To get the desired results, the heat must be monitored. Heat treatment is done in various techniques depending on the desired properties. The metal will be less or more brittle, stronger or weaker, or softer or harder depending on the technique that is used. Apart from the intensity of the heat, time is an important factor in the metal treatment; heating and cooling time should be controlled.
Metal hardening is the most known method of the heat treatment. The metal is heating to sufficient temperature forming a solid solution. To increase the hardness, impurities are added in the solution. It is vital to note that the quenching of the metal is done very quickly to ensure that those parties are trapped in the liquid metal.
The other method of the metal heat treatment is the case hardening. The process only makes the surface of the metal hard. Temperature and chemicals will be used to make the surface change. Carbon is the common metal that is used in the infusion.
Another method that you should know is the annealing. A metal is heated to a point where it gets physical transformation. Once heating is over, air cooling is done. Annealing is done on the copper, silver, brass, and aluminum. The results of the annealing is a metal that is ductile and softer; this will make it workable. During the machining, the metal will not crack because of these properties.
Steel has a special treatment process called normalization. It is heated at a temperature higher than in the annealing. Steel is held for a long time till it transforms physically. The objective of normalization is to make the steel easy to machine.
Tampering is a heat-treating process that is meant to make a metal more resilient. The process is mostly done on the iron-based alloys such as the steel. Although the alloys are hard, their brittleness limits their applications in some areas. After the tampering, the metal will be easy to machine. The process will change the ductility, hardness, and strength of the metal. The metal will be heated below the critical point.
