Abstract:
In recent years the need of having parts with high strength with low weight has grown exponentially and automotive industry has relied heavily on hot stamping technology to achieve this. Hot stamped parts can provide high strength and very good shape fixability for reduced weight compared to cold formed parts. This paper does a detail investigation Boron steel 22MnB5 and the different thermal parameters such as quenching rate, forming temperature, and quenching force that governs the phase transformation of the material, which in turn will decide the components’ strength and hardness. The paper also will investigate the role of part geometry in phase transformation. Optimizing the above mentioned parameters to achieve a minimum manufacturing time per part is one of the objectives of this paper. The extension of this work can be a study on altering the above mentioned parameters to achieve variable strength and hardness on a component to cater CAE crash teams to satisfy their safety needs.
