New metallic materials development by laser additive manufacturing

Dongdong Gu    Nanjing University of Aeronautics and Astronautics (NUAA), Nanjing, PR China

Abstract

The application of laser-based additive manufacturing (AM) technology to prepare novel structured high-performance materials and components is of unique interest. The special material incremental manufacturing (MIM) processing strategy and highly nonequilibrium metallurgical nature of laser processes favor the formation of bulk-form materials with unique microstructures and properties. This chapter summarizes our research work on the development of the nanostructured TiC reinforced Ti nanocomposites and microcellular stainless steel porous material, using the selective laser ...
