Grain refinement in unalloyed tantalum structure deposited using Wire + Arc Additive Manufacture and vertical cold rolling
G. Marinelli, F. Martina, S. Ganguly +1
Components manufactured via Wire + Arc Additive Manufacturing are usually characterised by large columnar grains. This can be mitigated by introducing in-process cold-rolling; in f…
Microstructure, hardness and mechanical properties of two different unalloyed tantalum wires deposited via Wire + Arc Additive Manufacture
G. Marinelli, F. Martina, S. Ganguly +1
An innovative way of producing large-scale unalloyed tantalum parts, based on the Wire + Arc Additive Manufacturing process, has been developed in this study. Two different unalloy…
Microstructure and thermal properties of unalloyed tungsten deposited by Wire + Arc Additive Manufacturing
Gianrocco Marinelli, Filomeno Martina, Supriyo Ganguly +5
Tungsten is considered as one of the most promising materials for nuclear fusion reactor chamber applications. Wire + Arc Additive Manufacturing has already demonstrated the abilit…
Development of Wire + Arc Additive Manufacturing for the production of large-scale unalloyed tungsten components
Gianrocco Marinelli, Filomeno Martina, Supriyo Ganguly +1
The manufacturing of refractory-metals components presents some limitations induced by the materials characteristic low-temperature brittleness and high susceptibility to oxidation…
Effect of shielding gas composition and welding speed on autogenous welds of unalloyed tungsten plates
Gianrocco Marinelli, Filomeno Martina, Supriyo Ganguly +1
Tungsten usually exhibits poor weldability and marked brittleness at room temperature. This cause tungsten welds to be affected by the evolution of cracks along the weld bead, whic…
