Project information
High strength lightweight steel can effectively save energy and cut emissions of vehicles, although it is more brittle than traditional low strength steel, which causes safety issue. This project tailors the coating structure of high strength lightweight steel to make this steel more ductile and ensure the safety.
The goal of vehicle CO₂ Emission Reduction
