Influence of in situ postweld heat treatment on microstructure and failure behavior of dual-phase steel resistance spot weld
The present study aims to investigate the effect of in situ postweld heat treatment (PWHT) on microstructure, tensile shear properties, failure mode, and hardness distribution of resistance spot weld of dual-phase (DP590) steel. Tensile shear properties were evaluated in terms of peak load and failu...
