Things You Need to Know About Metal Treatment
It is essential to know the difference between steel hardness and steel hardenability especially when it comes to steel modification. Hardenability focuses more on how a given type of metal can harden if it were subjected to extreme levels of heat. Steel hardening can only become as hard as the carbon content in the steel in question. It is also essential to remember that more carbon content in a metal tends to lead to a harder metal.
You would also need to remember that the hardenability characteristics tend to highly influence the resultant harness of a metal. One would need to know that metal hardening tends to involve ductility and toughness of the metal. Hardening of metal also tends to involve tempering which tends to involve holding of metal at a specific temperature before cooling the metal in question. The preheating process tends to reduce brittleness as well as make the carbon to precipitate into carbide particles.
One would also need to know that strengthening of the metal may also call for solid solution hardening, transformation hardening, cold working, among other processes. One would also need to remember that high strength in the aluminum alloy demands precipitation hardening. Cold working as a metal hardening strategy tends to focus on stressing the metal crystals as well as deforming the metal making is even harder. However, some processes tend to make the metal being worked on hard and brittle calling for more tempering to make it possible to work on the metal in question without splitting or cracking it.
Solid solution tends to focus on decreasing ductility and at the same time increasing strength of a metal. In the same line, transformation hardening focus on meeting the application requirements of a metal though adjusting the strength and the ductility of a metal. The grain structure of the metal in question also tends to change greatly through the heating process. The concurrent heating and cooling processes tends to focus on changing the metal properties adding value, applicability and durability of the metal in question.
Metal hardening also calls for a situation where the core metal is soft and ductile core with a wear resistant outer cover meant to reduce instances of wear. One would need to know that hardening of the outer layer of the metal tends to involve sinking of the metal up to a given depth. The intention of hot isostatic pressing tends to focus on removing any metal porosity improving its mechanical properties through compressing out any gas that may be trapped in the metal in question. HIP tends to be used in improving metals used in the aircraft engines and components.
