Selective Laser Melting of in-situ TiC/Ti5Si3 composites with novel reinforcement architecture and elevated performance

► Bulk-form TiC/Ti5Si3 in-situ composites were prepared by a novel SLM process. ► Interesting microstructural development of SLM-processed composites was disclosed. ► SLM-processed TiC/Ti5Si3 composites had high microhardness and wear resistance. ► Metallurgical mechanisms behind microstructures and properties were proposed.
