Effects of process parameters on microstructure and cracking susceptibility of a single crystal superalloy fabricated by directed energy deposition
As an advanced material forming method, additive manufacturing (AM) has been rapidly developed in many industry fields. Due to the non-weldability of nickel-based single crystal (SX) superalloys and complex solidification and stress conditions of AM process, hot cracks can easily form in depositions...
