Cracks suppression strategies for CoCrNi medium entropy alloy fabricated by laser directed energy deposition
Laser-directed energy deposition (l-DED) additive manufacturing of the CoCrNi medium entropy alloy is prone to cracking, especially with high laser heat input. Electron backscatter diffraction analysis showed crack formation and stress concentration at the high-angle grain boundaries. In addition, e...
