Investigation of the Properties of Fe-Zn and Al-Si Coated High-Strength Hot-Stamped Materials and Comparative Analysis of Delayed Cracking

Abstract

Automotive developments have spurred strong interests in lightweight, high-strength material for safety enhancement, emission minimization, and fuel economy enhancement. Due to their best strength-to-cost ratio, boron-manganese-steels processed by hot stamping are highly applied in structural body components. For maximizing service life and oxidation resistance in forming processes, protecting Fe–Zn and Al–Si coatings are utilized. Comparing delayed cracking resistance between Fe- and Zn-hot-stamped steels with various microstructures and residual stresses was aimed at by this work. Delayed cracking is one type of hydrogen-assisted failure mechanism whose appearance is microstructure-, residual stress-, and coating-dependent. An acid immersion test was accompanied by a mechanical delayed fracture test in order to create both laboratory and production conditions in the experiment. The results serve as guidelines for materials and coating selections for vehicles by illustrating the relationship between coating type and delayed cracking resistance.
