Abstract Scope |
Today, the field of materials for structural vehicle components faces the challenge of reducing weight while maintaining the required strengths in all operating conditions, the steels currently used show a heterogeneity of phases and are rarely fully specified or understood behavior at low temperatures, however, the abundant literature on the matter. It is the reason why we propose to generate new knowledge about the behavior of a type 15B24 heat treated steel. To achieve this, we propose to carry out the experimental study of heat-treated samples to obtain elastic limits of 150 KSI. Microstructural characterization and mechanical properties will be carried out at room temperature. We will determine the impact energy absorption capacity through Charpy tests at a temperature between ambient and -42ºC, as a reference of the operational limit of this steel, the temperature of the ductile to brittle transition will be determined. |
