Phase and Structural Transformations in Heat Resistant Alloys during Direct Laser Deposition

Abstract:

DLD, also known as Direct Laser Deposition, is an approached manufacturing technology. It is used to build full density metal parts directly from CAD files without using any modules or tools. A close look over the chemical composition and the microstructure of nickel based alloys will be shown in this paper.
