2. Isothermal treatment of steels
2.1 Influence of cooling
Isothermal treatments of steels are thermal processes in which the material is maintained at a constant temperature for a certain period of time, followed by controlled cooling. These treatments enable specific structures and properties to be obtained in steels. In these treatments, the influence of cooling is crucial in determining the metallurgical phases formed.
Figure 2 illustrates the different stages of isothermal treatment of steels, depending on the duration of isothermal...
