Planar-cellular-dendritic transformation in the fusion zone of a GH909 superalloy weldment
Solidification behaviors and resultant crystalline growth of primary gamma (γ) and γ/Laves phases were systematically investigated in a GH909 superalloy laser weldment. Results showed that horizontal microstructural evolution varied along the thickness direction under Marangoni force and eruption of...
