Combinatorial Investigation of the Ni–Ta System via Correlated High‐Speed Nanoindentation and EDX Mapping

Abstract

Correlative high-speed indentation and EDX were used for combinatorial mechanical property investigations for the first time, using a Ni-Ta diffusion couple. This was achieved with a novel approach using a simple correlation method which removed the necessity for complex statistical deconvolution. Correlative nanoindentation and EDX is demonstrated to be a powerful tool for future investigations.

High-Throughput High-Resolution Digital Image Correlation Measurements by Multi-Beam SEM Imaging

“…The recent emergence of integrated experimental tools that explicitly incorporate the physical nature of the deformation field at the nano-scale with representative fields of view at the millimeter scale now allows for new pathways to extract relationships between deformation fields and the structure and microstructure of materials. Experimental tools are, among others, high-resolution digital image correlation (HR-DIC) by scanning electron microscopy (SEM) [1], automated nanoindentation [2,3], high-throughput mechanical testing of miniaturized speci-mens [4] and high-speed atomic force microscopy [5]. They all capture physical signatures of deformation processes.…”

Filament Extrusion-Based Additive Manufacturing of 316l Stainless Steel: Effects of Sintering Conditions on the Microstructure and Mechanical Properties

“…Current nanoindentation systems enable the mechanical characterization of microstructures via rapid mapping of hardness and elastic modulus with sub-micron resolution across a millimeter-scale area. This advance has sparked numerous studies on mechanical microstructure characterization on a wide range of topics from combinatorial investigations on diffusion couples [29] to the extra-terrestrial microstructures of meteors [30]. Nanoindentation mapping has also been applied to study the microstructure and individual phase properties in duplex steels with varying processing conditions [31,32].…”
