| Abstract Scope |
Conventional in-situ characterization of materials at high temperatures in Scanning Electron Microscopes (SEM) has relied on resistive heating of bulk samples in oven-style crucibles. While these techniques can provide valuable insight in microstructural transformations of materials at elevated temperatures, they fail to capture the complex heating and cooling dynamics of real-world applications and more advanced manufacturing techniques such as Additive Manufacturing (AM). In this study, the Thermo Scientific µHeater was utilized to achieve ultra-fast heating and cooling rates on a variety of materials: Ti-6-4, Cu, Ag, Au, and Al alloys. Using the µHeater, a Micro-Electromechanical Systems (MEMs) device for in-situ experiments, enables acquisition of Energy Dispersive X-Ray Spectroscopy (EDS) and Electron Backscattered Diffraction (EBSD) while studying the microstructure inside the SEM. This more complete analytical characterization yields a better understanding of the material’s response under extreme conditions, further driving application-based material development. |
