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. Therefore generating manufacturing methods which can easily produce bulk tungsten samples with improved ductility is of key importance.
To investigate methods of improving ductility, tungsten nanopowders were sintered at low temperatures via hot isostatic press. The porosity of the samples were evaluated and strained to failure at various temperatures and strain rates to identify the ductile to brittle transition temperature. Additionally, samples were exposed to molten salts to evaluate their corrosion performance.
This work will identify key aspects of tungsten manufacturing that will enable the manufacture of ductile tungsten for use in advanced nuclear reactors. Future work involving alloying tungsten will improve ductility and thermal stability without significantly reducing corrosion resistance. |
