Accelerating Workflows for High-Throughput Nanoindentation.
Heterogenous microstructures are commonly employed across a wide range of applications as a tool for materials scientist to engineer the bulk properties, which can be seen in composite materials, multi-phase alloys or even surface treatments and coatings. Sometimes, property distributions can also arise due to processing history, with laser-based techniques with micro-scale heat affected zones being of particular interest recently. In most cases these structures are nano- to microscale in size, so to isolate mechanical properties from individual regions high-throughput nanoindentation-based techniques have become increasingly popular.
Two recent advances in nanoindentation mapping are highlighted here. First, the indentation depth controls the finest spacing that can be utilized without affecting the subsequent nearby indentations and thereby defines the resolution of a nanoindentation map. Displacement control is particularly important when mapping samples with highly variable hardness. To address this, recent enhancements for the Hysitron TI 990 TriboIndenter(Bruker, USA) allows for trigger points to be used to switch segments and feedback control all within one test. This enables high throughput workflow where translation between positions is followed by approach, surface detection, and a displacement-controlled indent. This mode works with both high load and low load transducers for addressing a large range of depths and spacings.
Secondly, relating the measured mechanical properties to local structure and composition is also essential for materials development. This can be done by switching instruments from the nanoindenter to the SEM, but this is time consuming and generally necessitates use of fiducial markers. To facilitate this process, the Hysitron PI 89 Auto (Bruker, USA) in situ SEM indenter utilizes a rotation-tilt stage to move the sample between 3 distinct positions: Indentation position, top-down SEM and EDS position, and 70°tilted EBSD position. The accompanying software enables the same sample region to be co-located in all 3 positions easily, such that regions of interest from an EBSD or EDS map can be directly targeted for indentation testing.

Nanoindentation and Micropillar Compression at Cryogenic Temperatures.
Mechanical reliability at low temperatures is required for environments in energy and aerospace applications. Due to its highly localized measurement capabilities, nanomechanical approaches can be useful for isolating individual regions within a more complex microstructure or component or testing of thin films. In general, both modulus and yield strength gradually increase with decreasing temperature, but more sudden shifts in behavior can also be observed, such as phase transformations or ductile-to-brittle transitions. In situ SEM testing enables visualization of the deformation mechanisms coupled with the measured mechanical properties helping complete the interpretation of the behavior. A low temperature control system has been developed for the Hysitron PI89 PicoIndenter (Bruker, USA) for in situ SEM testing that enables continuous temperature control from 130°C to 50°C. Independent temperature control on the tip and sample to enable proper temperature matching in vacuum and minimizes drift. The temperature dependent mechanical response of two metallic samples, Nitronic 50 and Tungsten, both by nanoindentation and micro-pillar compression.
