| Abstract Scope |
Tungsten is a desirable material for many applications due to its high melting temperature, corrosion resistance, hardness and strength. However, tungsten suffers from low ductility and poor thermomechanical shock behavior making it challenging to use in real-world industrial applications. Ultra fine grain tungsten shows excellent ductility but is difficult to manufacture and is not thermally stable. It is then imperative to devise new methods of manufacture to produce thermally stable ultra fine grained (UFG) tungsten with complex geometries to suit the growing needs of the nuclear industry. In this study, we treat tungsten nanopowders utilizing a hydrogen reduction process followed by PM-HIP processing utilizing glass canning methods to produce near net shape and fully dense (>90% theoretical) components with UFG characteristics. In future work we plan to mechanically alloy the tungsten nanoparticles with yttria nanopowders to enhance thermal stability without reducing ductility or corrosion resistance while improving creep resistance. |
