Investigation on Mechanical Properties of Boron Steel for Variation of Quenching Temperature and its Hot Press Forming Simulation

摘要

Hot Forming Die Quenching (HFDQ) process is a forming method which provides various advantages such as excellent mechanical properties and formability, good weldability, and little springback of the deformed materials. HFDQ technology can solve the inconsistency between crashworthiness and fuel economy for its high intensity and good formability at high temperature. While partial quenching can provide long elongation and high intensity on one product at different positions. In this paper, the investigation about the mechanical properties was carried on the Al-Si coated boron sheet after heating which can be considered as a data base of partial quenching. In addition, a relevant simulation model was built to provide theoretic basis for the practical manufacturing process. The data from this paper can be applied into the manufacturing process of B-pillar in automobile.
