Abstract Scope |
Understanding the mechanical properties of individual phases of multi-phase materials can often be hindered by the process of aligning separately measured microstructure and mechanical property maps, especially for high temperature applications. Here, we discuss a novel system designed to accelerate the identification of microstructure-mechanical property relationships using in situ nanoindentation testing. The system is a Bruker Hysitron PI89 Picoindenter system using a rotation and tilt stage to navigate between EBSD for microstructure identification and nanoindentation positions to assess site-specific material properties. This is coupled with a heating stage capable of attaining 1000 °C to directly assess the relationships between phase/orientation, temperature, and mechanical properties. Finally, we will apply the new system to understand phase transformations and the temperature dependence of mechanical properties at elevated temperatures in nickel based superalloys. |
