Our work on in-situ Transmission Electron Microscopy (TEM) experiments has facilitated Professor Sehitoglu’s team in conducting in-situ TEM cyclic tests. These assessments are crucial to understand the fatigue and fracture mechanisms in NiTi nanoscale shape memory alloys. Fatigue and fracture of shape memory alloys in the nanoscale: An in-situ TEM study, Scripta Materialia https://doi.org/10.1016/j.scriptamat.2023.115577 This …
Ph.D. Candidate Rephayah Black demonstrated the used of the Multi-Beam SEM technology to statically measure nm-scale plastic deformation events: High-Throughput High-Resolution Digital Image Correlation Measurements by Multi-Beam SEM Imaging, Experimental mechanics https://doi.org/10.1007/s11340-023-00961-y Background: Recent improvements in spatial resolution and measurement sensitivity for high-resolution digital image correlation (HR-DIC) now provide an avenue for the quantitative measurement …
Ph.D. Candidate Chris Bean investigated plastic localization in AM microstructure: International Journal of Plasticity Volume 159, December 2022, 103436 Additively manufactured 316L stainless steels display significantly higher yield strength than their as-cast or wrought counterparts. This is associated with the micro-scale cellular structure and complex grain and sub-grain structure, resulting from high cooling rates occurring …
Engineers can now capture and predict the strength of metallic materials subjected to cycling loading, or fatigue strength, in a matter of hours – not the months or years it takes using current methods. In a new study, researchers from the University of Illinois Urbana-Champaign report that automated high-resolution electron imaging can capture the nanoscale …
The paper entitled “A Multi-modal Data Merging Framework for Correlative Investigation of Strain Localization in Three Dimensions” has been selected as the JOM Editor’s Choice for November 2021.
