Abstract

In this study, the effect of hydrogen on the tensile shear strength of spot-welded transformation-induced plasticity (TRIP)-aided martensitic (TM) steel sheet was investigated. The tensile shear tests were carried out on a tensile testing machine using the spot-welded specimen which was spot-welded at the lapped portion of 30 mm×30 mm using specimen with dimensions of width of 30 mm and length of 170 mm at crosshead speeds of v=0.5 to 100 mm/min with and without hydrogen. The results were summarized as follows.

期刊介绍： The journal ISIJ International first appeared in 1961 under the title Tetsu-to-Hagané Overseas. The title was changed in 1966 to Transactions of The Iron and Steel Institute of Japan and again in 1989 to the current ISIJ International. The journal provides an international medium for the publication of fundamental and technological aspects of the properties, structure, characterization and modeling, processing, fabrication, and environmental issues of iron and steel, along with related engineering materials.
