How Beneficial Heat Treatment is to Metals
When it comes to the manufacturing processes, there are some of the materials that will at times require that they be subjected to some procedures that will change their grain structure and composition. Heat treatments are actually some of the methods that have been used for quite some time for the sake of changing metals physical properties as such improving them to be used in a wide range of industries. The change in the physical properties of the metals is achieved by use of some controlled heating and cooling procedures.
By far and large, the heat treatments happen to differ and this is majorly dependent on the type of metal and the physical properties that are so desired for the functioning of the given parts. Strength often being the core need, it is as such important to ensure that the correct heat treatment procedures are followed to ensure that this is achieved.
Like has been mentioned above, apart from aiding in altering a metal’s physical properties, heat treatments as well help a great deal in some other manufacturing processes. Following a heat treatment procedure, a material will get to attain some of the following benefits-relieving stresses and as such being so much easier to work on and above this is the fact of added strength. Alongside this is the fact that this as well makes the material a lot more resistant to wear and tear as a result of the fact that the wear and tear resistance characteristics will be added to them, and as well the material will have been made a lot more ductile or flexible. Steel is actually one of the materials that tends to benefit from heat treatment processes more so in the manufacturing process such as hot forming and welding as these often see high build up of stresses. There are as a matter of fact a variety of the kinds of heat treatments and some of these are as mentioned under as the website explains.
The first kind is annealing and solution annealing. Annealing is so effective and an ideal method more so looking at the fact that it makes the grain structure refined, making it more uniform and so easy to work with. Solution annealing particularly helps achieve corrosion resistance and better ductility.
One other kind of metal het treatments is that known as hardening and tempering. Hardening can be performed on certain kinds of steel metals that have a particular composition of carbon in them and it always involves the heating of the material to such high temperatures as up to 900 degrees after which they are speedily cooled as this page shows. Tempering will then follow and this is where the material is further taken to another cycle of heating which makes the materials more ductile.
