7%-10.9% to 1.1%-2.6%, Max. bending deflection decreased from 1.3-3.4 mm to 0.4-1.0 mm, and flatness error dropped from 0.9-3.3 mm to 0.3-0.7 mm. The fractographic analysis reveals that the crack initiation is related to alternative V-shape micro-notches at the laser-affected zone; the predominant fracture mechanism involves mode II microvoid coalescence at the main fracture plane; smaller and less elongated dimples were formed in 40Cr steels due to higher number density of grains and pinning effect of second-phase particles
