Additive Manufacturing of Oxide Dispersion-Strengthened Superalloys

Oxide dispersion strengthening is a unique method of increasing an alloy's strength at temperatures near 1000 °C, however, the conventional production method is time and cost intensive. Metal 3D printing can sidestep many of these issues, but presents several of its own. In this thesis, we explore how to optimise these materials for 3D printing by tailoring their initial production and heat treatment for strength and resistance to slow deformation at extreme temperatures. These findings suggest future directions for the development of next-generation materials in aeroplane and rocket engines.
