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...

As the desire for hydrogen as a clean energy source intensifies, the current midstream strategy is to transport hydrogen and hydrogen fuel blends through legacy piping networks. There is limited data on the impact of hydrogen transport on the properties (fatigue, fracture toughness, crack growth rates, etc.) and life cycles of these pipe systems. In...
