| Abstract Scope |
High throughput nanoindentation techniques are popular for visualizing and measuring the differences in elastic and plastic properties across various heterogeneous microstructures of materials. Since nanoindentation can typically fit several tests into a particular grain or phase, these techniques can also be used to rapidly gather statistics. Some example applications include multi-phase alloys, heat affected zones from laser-based processing and composite materials. Recent advances in the software and controller for the Hysitron TriboIndenter 990 (Bruker, USA) allow mixed feedback modes and triggers in a single load function, enabling consistent indentation depth and spacing even across regions of highly varying hardness. Easy correlation of structural and chemical information from in situ SEM indentation and high throughput analysis by clustering methods will also be presented, which are important components towards rapidly developing structure-property relationships at the small scale. |
