Effect of Direct Energy Deposition Process Parameters on Single-Track Deposits of Alloy 718

Effect of Direct Energy Deposition Process Parameters on Single-Track Deposits of Alloy 718

The effect of three important process parameters, namely laser power, scanning speed and laser stand-off distance on the deposit geometry, microstructure and segregation characteristics in direct energy deposited alloy 718 specimens has been studied. Laser power and laser stand-off distance were fou...
