A novel and high-efficiency dual-electron gun concurrent preheating additive manufacturing technology: suppressing thermal cracks in non-weldable IN738LC nickel-based superalloy by mitigating temperature fluctuations
The process of electron beam powder bed fusion (PBF-EB) is recognised for its efficacy in preparing non-weldable nickel-based superalloys, leveraging high-temperature preheating to minimise stress-related issues. Traditionally, the PBF-EB process involves pausing the preheating scan during printing...
