Zinc Effects of Mechanical Behavior of AHSS Welds
- Advanced high strength steels (AHSS) are being increasingly used in automotive structures to reduce vehicle weight and increase fuel efficiency.
- AHSS are zinc coated to protect the steel from corrosion. However the steel-zinc system can lead to liquid metal embrittlement (LME) during resistance spot welding.
- Cracked welds are a concern for the strength and quality of AHSS joints. Further understanding and mitigation of LME cracking is needed before AHSS can be widely implemented.
