Porosity in cored-wire-arc directed energy deposition of TiC/Al composite: formation mechanism and inhibition strategy

Virtual and Physical Prototyping
Porosity is an unavoidable problem in aluminium alloy wire-arc directed energy deposition (DED), becoming even more prominent in aluminium-matrix powder core wires, which significantly limits their performance and application potential.
