| Abstract Scope |
Rapid quantification of the mechanical properties of individual phases of multiphase materials can often be hindered by the slow process of aligning separately measured microstructure and mechanical property maps, especially for materials deformed at high temperatures or which undergo temperature-dependent phase transformations. Here, we discuss a novel system designed to streamline the process of correlating microstructure with mechanical properties using in situ nanoindentation testing. The system is a Bruker Hysitron PI89 Picoindenter system using a system of X, Y, rotation and tilt translations to directly target microstructures from EBSD with nanoindentation to assess site-specific material properties. This is coupled with a heating stage capable of attaining 1000 °C to directly assess the relationships between temperature, phase/orientation, and mechanical properties. We apply the new system to understand the phase- and temperature-specific mechanical properties in nickel-based superalloys. |
