    1. 145. EFFECT OF Zn-COATING PROCESS ON LIQUID METAL EMBRITTLEMENT OF TRIP STEEL

      Thermal Joining (Spot Welding) and Liquid Metal Embrittlement
      Oral Presentation

      The resistance spot welding is widely employed by automotive manufacturers because of its low cost and fast process. However, when the galvanized TRIP steel plates are joined by resistance spot welding, cracks are generated by liquid metal embrittlement (LME) because the substrate gets exposed to liquid zinc. These cracks deteriorate mechanical reliability of welds and limit the application of...

    2. 162. QUANTITATIVE ASSESSMENT OF THE INFLUENCE OF STARTING MICROSTRUCTURE ON THE LIQUID METAL EMBRITTLEMENT SUSCEPTIBILITY OF 3rd GENERATION ADVANCED HIGH STRENGTH STEELS

      Thermal Joining (Spot Welding) and Liquid Metal Embrittlement
      Oral Presentation

      Third generation advanced high strength steels (AHSS) were developed as automotive structural materials capable of enhancing vehicle fuel efficiency and crashworthiness. The use of zinc (Zn) coated AHSS is limited by Zn-assisted liquid metal embrittlement (LME) that leads to surface cracking during high temperature processing. It has been reported that AHSSs are generally more sensitive to...
