Nanocrystalline tungsten was obtained by selective laser melting (SLM) in the present work. The microstructures and compositions revealed that the nanocrystalline tungsten could be fabricated via the SLM method using pure tungsten powder. It was found that the produced nanocrystalline tungsten microstructure could be regarded as a resultant of solid forces by laser, which grow along a special crystal surface. The metallurgical mechanisms for the formation of such a novel structure through SLM process were also addressed.
