  • Failure mode of M130 martensitic steel resistance-spot welds = Način porušitve uporovnih točkastih varov pri martenzitnem jeklu M130
    Pouranvari, Majid ; Mousavizadeh, Seyed Mostafa
    This paper discusses the transition from the interfacial to the pullout failure mode for the M130 martensitic, advanced high-strength steel (AHSS) during a quasi-static tensile-shear test. It was ... studied whether the conventional/industrial weld-size criteria can produce pullout failure modes for M130 spot welds. The minimum fusion-zone size required to ensure the pullout failure mode during the tensile-shear test is estimated using an analytical model, taking into account the weld metallurgical characteristics, with good accuracy. Based on the theoretical analysis it was concluded that the failure-mode transition in M130 resistance-spot welds is influenced by the sheet thickness, the fusion-zone hardness and the intercritical heat-affected-zone hardness.
