| Abstract Scope |
The transportation section is ranked as the 2nd contributor to global warming for its production and use of fossil fuel powered vehicles. As the industry transitions to an all-electric future, greenhouse gas emission from vehicle’s tailpipe will become zero with clean electricity. Meanwhile, decarbonization of vehicle production and adoption of low-carbon footprint materials are critical to achieve carbon neutrality. This talk summarizes recent progresses on the development of low-carbon footprint alloys and component fabrication processes: 1) a coating-free press hardening steel with 1.7 GPa tensile strength that can be made with 50% steel scrap, and 2) a new casting aluminum alloy, using a significant percentage of post-consumer aluminum scrap, that is suitable for both low pressure and high pressure die casting processes. The potential of simplifying materials selection for easy recycling of end-of-life vehicles is also discussed, with the newly proposed concept of UniSteel and UniCast. |
