This seminar is part of the Jones Seminars on Science, Technology, and Society series

This talk will survey work performed by the speaker on intermetallic compounds, ice and (snow) firn. The work on intermetallics has progressed from understanding phenomena such as the yield stress anomaly and strain-induced ferromagnetism in compounds such as FeAl and Fe2AlMn to understanding the strengthening mechanisms in recently discovered high-strength FeNiMnAl spinodal and eutectic alloys. The talk will emphasize the use of a variety of transmission electron microscopy-based techniques and atom probe tomography in these studies.

The talk will also outline our progress in characterizing the microstructure of ice cores and firn cores using both X-ray micro computed tomography and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy and electron backscattered diffraction.
