Benefits of Metal Treatment
It is essential to know the difference between steel hardness and steel hardenability especially when it comes to steel modification. One would need to know that hardenability tends to determine how much a given type of still can harden during the welding process. You would always need to avoid confusion between hardenability and hardness with steel’s maximum hardness tends to be a function of its carbon content. 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. Among the goals of hardening a metal includes increasing its ductility as well as toughness. 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. One would also need to know the benefits of preheating a metal to reduce brittleness created by the first heating as well as allowing the carbon content to precipitate into carbide particles.
Among other processes involved in the strengthening of the metal tends to include cold working, solid solution hardening, transformation hardening, and precipitation hardening. Precipitation hardening tends to be a perfect match when it comes to aluminum alloy. On the other hand, cold working of a metal tends to deform it and stress its crystal structures making the metal in question to become harder. There tend to be instances when the hardening tends to make the metal brittle and make it prone to splitting and cracking which calls for tempering of the metal in question.
One would also need to remember that the solid solution focus on increasing the strength of the metal and at the same time make sure that the ductility of the same is reduced significantly. The transformation hardening is also known to be used in the adjustment of a metal’s ductility and strength. 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.
In some cases, the only metal that demands hardening includes the metal at the outermost layer and leave the metal at the core soft. When hardening the outer layer, carbon tends to be used and tends to be sunk up to a given depth. One would also need to know about hot isostatic pressing as yet another imperative process. The hot isostatic pressing may be involved when in improving titanium, chrome, as well as stainless steel metals used in aircraft components and engines.
