ADDITIVE MANUFACTURING TECHNIQUES TO REDUCE CHEMICAL SEGREGATION

原文（中国語）

A method of making a component using additive manufacturing (AM) techniques that selecting an AM manufacturing process suitable for making the component; selecting a material for the component that is compatible with the AM manufacturing component; selecting and programming AM process steps into a selected AM apparatus; and building the component on the selected AM apparatus using the selected AM process steps. The AM process steps are selected to produce a plurality of melt pools that reduce material segregation in the finished part. The component exhibits reduced material segregation compared to making the material with a consumable electrode remelting process. The component made with AM techniques includes a region exhibiting reduced material segregation compared to making the material with a consumable electrode remelting process.
