Abstract

Micro- and nanoscale in-situ investigations of engineering alloys’ behaviours during deformation [ 1- 5] and/or heating [ 6- 8] have intensified in recent years, partly driven by advances in in situ characterization tools, enabling new insights into material behavior. Here we examine the capabilities and potential of automated in-situ characterization capabilities of the newly developed Tescan and Newtec In-Situ Testing (TANIST) system. It is a specialized system for conducting thermal and mechanical tests while simultaneously capturing microstructural observations at high spatial and temporal resolutions. This system supports full automation, enabling continuous 24/7 experimentation and facilitating measurements over a broader range with finer load and temperature increments than previously achievable [ 9]. The system facilitates the capture of plasticity localization through high-resolution digital image correlation (HRDIC), which is crucial for understanding the damage and failure mechanisms in engineering alloys. Simultaneously, precise monitoring of microstructural changes, including phase transformations and chemistry distribution evolution, is possible using complementary detectors such as electron backscatter diffraction (EBSD) and energy dispersive X-ray spectroscopy (EDX). Furthermore, the concurrent development of data analysis tools, such as DefDAP [ 10], a Python library for correlating EBSD and HRDIC data, enhances the wealth of information obtainable through in-situ testing.

This talk will start by presenting an introduction to the TANIST system, developed by Tescan and NewTec in collaboration with the Henry Royce Institute. The first system in Australia is now available at Monash University within the Monash Centre for Electron Microscopy (MCEM). Several case in situ studies will be presented, including in-situ loading studies utilizing EBSD and HRDIC on a TRIP-assisted advanced high strength steel, in-situ loading investigations employing EBSD and in-situ heating observations using EDX and EBSD on hot isostatic pressed (HIPped) Ti-Fe alloys.
