Effects of processing parameters on crystal growth and microstructure formation in laser powder deposition of single-crystal superalloy

A self-consistent three-dimensional (3D) mathematical model was developed to predict the crystal growth and microstructure formation in the laser powder deposition (LPD) of single-crystal (SX) superalloy. The effects of the governing processing parameters of LPD, i.e. laser power, scanning speed, po...
