Fig. 4: Effect of laser power on the formation of SGs.
From: In situ observation of crystal rotation in Ni-based superalloy during additive manufacturing process
a Number of diffraction spots as a function of time at a laser power of cm W. The orange, grey, purple and red rectangular zones denote Laser Heating Period I, Laser Heating Period II, Laser Heating Period III and solidification and SG formation period, respectively. b Number of diffraction spots as a function of the laser power. Error bars indicate the standard deviation coming from 20 repeatedly recorded data in the same sample. c Ex situ EBSD images at different laser powers.
