金属PBF-LB法でのボーリング発生条件

抄録

To elucidate the phenomenon of molten condensation in the metal PBF-LB method, we present the conditions of borehole generation based on the analysis of the wetting phenomenon between the molten pool/powder and the molten pool shape by the Rosenthal solution for the moving heat source and show it on the scanning speed - laser power process map. The results are compared with the experimental results of the Inconel 718 under high-speed scanning conditions.
