New technology makes automotive steel tough and light, energy-saving and safe

Energy saving, emission reduction and safety improvement arecarTwo important development directions for industry. In recent years, Northeastern University has made breakthroughs in theory and technology. Independently developed a new high-toughness aluminum-silicon coating process for automotive steel to increase its toughness by 20%-30%. At the same time, it has also contributed to the development of automobile lightweight.New technology makes automotive steel tough and light, energy-saving and safe!

Traditional aluminum-silicon coated automobile steel plates have excellent performance in abrasive protection, dimensional accuracy of parts, corrosion resistance, etc., but their defects are also obvious: insufficient toughness. "Insufficient toughness will directly lead to the failure and fracture of automobile crash safety components. Professor Yi Hongliang, State Key Laboratory of Rolling Technology and Continuous Rolling Automation of Northeastern University, said that if this bottleneck is broken, the door anti-collision beams can be further strengthened.bumper, B-pillar and other safety structural parts.

Professor Yi Hongliang’s research team found that during the austenite heating process, the al-si coated steel sheet produces a large amount of carbon enrichment near the interface between the 22mnb5 matrix and the diffusion layer, and high-carbon martensite is formed in the subsequent cooling process. It is the extremely low toughness of the high-carbon martensite layer that significantly reduces the toughness of the aluminum-silicon coating product.

Based on this theory, it was found that without changing the composition of the coating and the base alloy, the Yi Hongliang team adopted a combination of "thinning the coating" and "optimizing the heating process", which greatly improved the aluminum-silicon coating. toughness. Products, and greatly increase the bending fracture strain, reduce the risk of delayed cracking.

This new technology has also received great attention from the industry, and the theory has been quickly transformed into practical technology, and high-toughness aluminum-silicon coated hot stamping steel products have been trial-produced in the batch industry. This new material can achieve the same strength as existing materials and improve toughness, thereby improving the safety performance of auto parts.

"This technology started from theoretical innovation and formed independent intellectual property rights. Not only Chinese invention patents have been authorized, but international patents are also being applied for. The industrialization of this technology will be in the stage of more than 3 million tons (nearly 1 million tons in China). Play an important role and contribute to the lightweight development of China's automobile. This is also China's contribution to the world's automobile industry. Academician Mao Xinping of the Chinese Academy of Engineering said.
