Formation of nanocrystalline tungsten by selective laser melting of tungsten powder

Formation of nanocrystalline tungsten by selective laser melting of tungsten powder

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 micro...
