| Abstract Scope |
Material solidification and microstructure evolution during additive manufacturing (AM) occurs under high heating and cooling rates (up to 1000C/s). Moreover, the introduced heat extends beyond the thickness of each printed layer, resulting in additional thermal effects along with the printing geometry. Understanding the effects of these cyclic thermal processes on microstructure formation and evolution is crucial for achieving the desired component property and functionality.
This study demonstrates the opportunity of using MEMS-based heaters for in-situ microstructure investigations of bulk-like specimens under high heating and cooling rates in the scanning electron microscope (SEM). By combining experimental measurements and COMSOL simulations, we present insights into the accuracy and reliability of mimicking AM thermal processes for in-situ microstructure characterization. |
