Abstract Scope |
Capturing the mechanical response of three phase (solid, liquid and gas) semi-solid materials at high temperatures is particularly challenging due to the strongly non-linear temperature dependence of the properties and the reactive nature of many material’s under these conditions. Using a series of in house thermomechanical environmental rigs we measure the mechanical and rheological properties of materials in temperature ranges from -20 to 1600C whilst on a synchrotron beamline. This enables correlation of the evolving microstructural features to the mechanical properties using in situ radiography, tomography and diffraction The benefits and limitations of these techniques measuring the properties for systems ranging from nickel based superalloys to the flow of molten magma as it bubbles and volatilises. The insights obtained are inform and validate computational models to help design components for transport applications through to predicting volcanic eruptions. |
