Revealing melt pool dynamics and mechanisms of powder spattering in laser powder bed fusion of nickel-based superalloy by in-situ high-speed synchrotron and optical imaging

Spatter formation during laser powder bed fusion (LPBF) process of nickel-based superalloys detrimentally affects the processing reliability and consequently impacts part quality through defects and powder bed contamination. However, due to high-Z characteristics of superalloys,...
