Effect of Hydrogen on Tensile Shear Strength of Spot-Welded Ultrahigh-Strength TRIP-Aided Martensitic Steel Sheet
In this study, the effect of hydrogen on the spot-welded tensile shear strength of transformation-induced plasticity (TRIP)-aided martensitic (TM) steel sheet was investigated. The tensile shear tests were carried out on an Instron-type universal testing machine using the tensile shear specimen which was spot-welded at the lapped portion of 30×30 mm2 using specimens with dimensions of width of 30 mm and length of 170 mm at crosshead speeds of 0.5-100 mm/min without and with hydrogen. The results were summarized as follows.
