Abstract
The influence of the technological parameters of selective laser melting (SLM) on the structure–phase state of a ZhS6K-VI nickel superalloy synthesized is studied by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. A nickel solid solution, an ordered γ' phase, and carbide inclusions form in the alloy at a scanning speed of 600–1200 mm/s, a laser beam power of 170–200 W, and various melting strategies. The following texture is shown to form in the alloy during SLM: the laser scanning plane predominantly coincides with the crystallographic {100} plane. The lower the scanning speed or the laser power, the stronger the texture. The alloy of found to be susceptible to cracking, which decreases with increasing scanning speed.
