The H-coupon test, developed a few years ago to evaluate cracking behavior in spot-welded advanced high-strength steels (AHSS), has recently been applied to galvanized third generation AHSS. Two types of cracking have been observed in the tests of these steel grades – interfacial and zinc liquid metal embrittlement (LME). This research is discussed in Application...
