Abstract Scope |
Measuring 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 many of the material’s reactive nature. To help address this, we have developed a series of thermomechanical environmental rigs to measure the mechanical and rheological properties of materials in temperature ranges from -20 to 1600C whilst on a synchrotron beamline. This allows us to correlate the properties to the evolving microstructural features at the micron scale using in situ radiography, tomography and diffraction We illustrate the benefits and limitations of these techniques measuring the properties for systems ranging from aluminium alloys to cobalt-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. |
