Time-Dependent Oxidation and Scale Evolution of a Wrought Co/Ni-based Superalloy
Cameron. Crabb, Zachary. T. Kloenne, Samuel. R. Rogers +4
Understanding how protective oxide scales evolve over time is necessary for improving the long term resistance of superalloys. This work investigates the time-dependent oxidation b…
Mechanisms of Elevated Temperature Galling in Hardfacings
Samuel R. Rogers, David Stewart, Paul Taplin +1
The galling mechanism of Tristelle 5183, an Fe-based hardfacing alloy, was investigated at elevated temperature. The test was performed using a bespoke galling rig. Adhesive transf…
Dislocation distribution, crystallographic texture evolution and plastic inhomogeneity of Inconel 718 fabricated by laser powder-bed fusion
Jalal Al-Lami, Thibaut Dessolier, Talha Pirzada +1
Plastic inhomogeneity, particularly localised strain, is one of the main mechanisms responsible for failures in engineering alloys. This work studied the spatial arrangement and di…
Adhesive Transfer operates during Galling
Samuel R Rogers, Jaimie Daure, Philip Shipway +2
In order to reduce cobalt within the primary circuit of pressurised water reactors (PWRs), wear-resistant steels are being researched and developed. In particular interest is the u…
The Interaction of Galling and Oxidation in 316L Stainless Steel
Samuel R. Rogers, David Bowden, Rahul Unnikrishnan +5
The galling behaviour of 316L stainless steel was investigated in both the unoxidised and oxidised states, after exposure in simulated PWR water for 850 hours. Galling testing was…
