“…Biro et al concluded that HAZ softening of DP steel weldments by martensite tempering depends on the nucleation and growth of cementite [22]. Xu et al and Lakshminarayana et al found that the softer fusion zone formed in laser welding consists mainly of martensite, ferrite, and bainite; an almost fully martensite structure was observed, attributable to the faster cooling rate [23,24]. Zhao et al studied how laser welding speed affects the microstructure and properties of DP steels of 600, 800, and 1000 MPa grades; they concluded that a linear relationship existed between the carbon equivalent and the hardness of the fusion zone [25].…”
