HLF 1 taken with SEM. Eutectic crystallization texture in iron silicides from a fulgurite from lower Michigan (lightning strike glass). Submitted by Christopher Stefano, Associate Curator, A. E. Seaman Mineral Museum.
Materials Science doctoral candidate Deji Fadayomi, and professors Paul Sanders and Gregory Odegard, are working on these precipitation-strengthening mechanisms in aluminum-based alloys. This atomic-resolution image and elemental maps of precipitates were obtained in aberration-corrected scanning transmission electron microscope (AC-STEM) at Michigan Tech’s Applied Chemical and Morphological Analysis Laboratory (ACMAL) to better understand alloy behavior at an atomic level.
