Metals like aluminum and steel can be treated to change their physical properties. These heating and cooling methods must be carefully executed in order to create the desired effects. For example, a hardening process that is not done properly could cause a metal to become too brittle. Following are some basic terms that are related to heat treating metals.
Annealing – This is a method of heat treating metal. This chemical process softens the metal, altering properties light strength and hardness.
Degassing – This is a heat treatment method that removes gas from the metal. Metals from titanium to aluminum can be degasses, though it is not as necessary for some kinds of metal.
Hardening and Tempering – This method requires heating and cooling of a metal. This is a process for hardening a metal, and it can also create a bright finish on the sword, beam, or other finished product. Steel can be further strengthened through hardening and tempering.
Normalizing – This process is done by manufacturers to refine the metal’s grains. The immense heat involved in normalizing causes a phase change in the microstructure of the substance.
Sintering – Sintering can be done to create an alloy, or combination of different metallic substances. Sintering is when manufacturers heat metals to just below the melting point. This makes them more likely to bond with other metallic powders.
Stress Relieving – Stress relieving is accomplished by using a slower cooling phase. This decreases stress in an alloy or other created material.
Vacuum Heat Treating – This process involves heating and cooling a metal in a carefully controlled environment. This allows for higher quality metals, and it creates a clear and bright surface.
Heat treating metal and alloy manufacturers will work with steel and aluminum to make them into different products. They can make something as small as swords with sharp tips to large aircraft pieces. A lot goes into making sure the chemicals are all correct when going through the heat treating process. It is used to change both the physical and chemical properties of the metal in order to make it into something. The microstructure has small crystals, which are often called grains or crystallite. The crystallite is what a heat treating company will look at to determine the mechanical behavior of the metal. There are various methods that a company will use, including case hardening, selective hardening, precipitation strength, tempering, quenching, and annealing. If you're looking for a certain type of method to be used you can ask the company if they have experience with it and how much they charge to have it done. By controlling how fast diffusion and cooling occurs the heat treating metal manufacturer can change the metal's properties. Look for reviews on different companies and see if one is known to work better with steel rather than aluminum. Call and ask if they have a sale on any of the products they're selling. Compare prices with your other choices to see where you get the best deal. The Internet and phone book will provide you with names of heat treating metal manufacturers and their phone numbers. Some may have websites that can give you a better look at the company and what services they provide.
