摘要
Effect of hydrogen on spot welded tensile properties in ultrahigh strength TRIP-aided martensitic (TM) steel sheet was investigated for automotive applications. Tensile test was performed on a tensile testing machine at a crosshead speed of 1 mm/min (strain rate of 2.8×10−4/s), using base metal and spot welded specimens with or without hydrogen charging.
