摘要
Effect of heat-affected zone (HAZ) softening on tensile strength (TS) and total elongation (TEl) of spot welded ultrahigh strength TRIP-aided martensitic (TM) steel sheet was investigated for automobile applications. Tensile test was performed on an Instron type tensile testing machine at a crosshead speed of 3 mm/min (strain rate of 8.3×10–4 s–1), using spot welded specimen.
