Investigation and Comparison of Process Parameters for Advanced High Strength Steels for Next-Generation Vehicles

Innovations are now required in the automotive industry, as well as in many other industries, due to environmental concerns and initiatives to minimize greenhouse gas emissions. The use of lightweight materials has grown for this purpose and specifically created new generation high-strength steels have begun to be used. In this work, the hot stamping method was used to examine the impact of process variables on the mechanical characteristics and microstructures of materials from two different steel manufacturers. The outcomes of varying the soaking time and austenitizing temperature were examined in order to analyze the process conditions. The analyses led to the selection of 890°C as the ideal austenitizing temperature and 240s as the ideal soaking time in the furnace. It was found that as the soaking time in the furnace decreased, it improved the microstructure and indirectly the mechanical characteristics. This study has the feature of guiding the determination of the optimum parameters for the materials of different manufacturers starting from the manufacturing stage and then in the material selection stage.
