In simple terms, heat treatment is the process of heating the metal, holding it at that temperature, and then cooling it back. During the process, the metal part will undergo changes in its mechanical properties. This is because the high temperature alters the microstructure of the metal. And...
This is the 100th column for "The Heat Treat Doctor"! So, how do we celebrate? By asking ourselves the most fundamental of questions: What is heat treating, and why do we do it? Let's learn more.Daniel H. HerringIndustrial Heating...
<!—->Secondary Processing: Heat treating is applied to metal parts to enhance their strength and make them more durable for their application. Grinding is used to finish parts requiring high surface quality and dimension accuracy. Wire EDM: Wire electrical discharge machining shapes metal materials...
Laser heat treatment is a surface engineering technique that uses high-power laser beams to selectively modify metal surfaces' composition, structure, and properties. It is commonly applied to steel and cast iron materials that require enhanced wear, fatigue, and corrosion resistance. ...
While conventional plastics retain heat, plastics containing thermally conductive fillers distribute heat and carry it away from the heat source. The thermal conductivity of conductive plastics is not as high as that of metal, but conductive plastics can be just as effective as metals in thermal man...
The heat affected zone (HAZ) is a non-melted area of metal that has undergone changes in material properties as a result of being exposed to high temperatures. These changes in material property are usually as a result of welding or high-heat cutting. The HAZ is the area between the weld...
Once the desired temperature has been reached the temperature is held for a fixed period. A rough guideline for this proposes one hour per inch of thickness, although this differs depending on the type of metal being treated. The heat relieves the internal stresses in the metal, after which ...

For example, there is a reason automobiles, airplanes, and bridge structures are made from metal and not plastic. Not only is aluminum stronger and better at resisting direct hits from flying debris, but aluminum is also more stable. High temperatures and direct exposure to the sun can weaken...
Quenching involves rapidly cooling metal to harden it, while tempering is a subsequent heat treatment that reduces brittleness and increases toughness by reheating and then cooling the metal at a controlled rate.
