Structural materials — they’re everywhere!

From the blades of the gas turbine engine propelling you across the country (and probably providing some of the electricity you use everyday), to the tiny devices that deploy your airbags, project your powerpoint slides and reorient the screen on your smartphone when you turn it — the mechanical integrity of the materials that make up these devices is crucial to their durability and performance.  Our group is interested in the relationships between mechanical properties and microstructure across a variety of length scales and time frames. In many important applications, how the properties change over the lifetime of a component are closely linked to phase and microstructural evolution. Studying this process requires some traditional characterization techniques like transmission electron microscopy and x-ray diffraction, but also involves novel approaches such as micro-mechanical tensile tests or elevated temperature microscopy.

    Postdoc OpportunitiesDecember 8, 2023

    The number of programs within our research group emphasizing the interactions between hydrogen and structural materials is growing.  I am seeking a dedicated scientist interested in expanding their experience in materials characterization (mechanical and microstructural) to understand these hydrogen interactions across a range of temperatures and alloy chemistries.  The selected candidate will be responsible for performing experiments, […]

  • Interact with the Krogstad group at TMS in San Diego!February 16, 2020

    Several members of the Krogstad group as well as many collaborators will be heading to San Diego soon for the Annual TMS meeting. Prof. Krogstad will be presenting at the Young Professionals Tutorial Luncheon (SDCC 6A) on Tuesday at noon. You have to register for lunch but you can listen to the talks for free! […]

  • Opportunities for new graduate studentsFebruary 12, 2020

    We’re excited for the upcoming graduate visit weekends for MatSE @ Illinois.  The Krogstad group will be looking for new students next fall on a variety of potential projects, but especially to join our effort to understand intrinsic toughening mechanisms in polycrystalline ceramics (Deformation mechanisms in high performance ceramics)
