Effect of liquid metal embrittlement cracks on mechanical behavior in advanced high strength steel
Liquid metal embrittlement (LME) is a serious and prevalent issue during resistance spot welding with the new generation of galvanized advanced high strength steels. Extensive studies focus on the elimination of LME cracking during the welding process; however, little research has been performed on the mechanical performance of spot welds if LME is present. Additionally, mechanical performance at low temperatures is of interest due to the range of operating conditions automobiles are exposed to. An experimental matrix was established using three ranges of crack sizes, three testing configurations ...
