Heat treatments are operations involving heating, maintaining the temperature, followed by cooling, with the aim of giving a metal piece the most suitable properties for its use. They allow for a significant improvement in the mechanical characteristics of steel with a determined composition. Generally, a heat treatment does not alter the chemical composition of the alloy but brings about the following modifications:
- Constitution (state of carbon and allotropic form of iron).
- Structure (grain size and distribution of constituents).
- Mechanical properties.
The purpose of these treatments is to enhance the characteristics of materials and make them more suitable for a given application, based on the following modifications:
- Increase in tensile strength and yield strength (Rem, Re), providing better performance of the element.
- Increase in hardness, allowing parts to better resist wear or impact.
