During this one-hour event, guest speaker Dr. Xinghang Zhang (Purdue University) will showcase PI 89 capabilities on CoAl intermetallics, TiO₂, and nanotwinned aluminum, where many interesting deformation phenomena can be observed. A live demonstration of high‑temperature mapping with the PI 89 will also be presented by Bruker experts, along with analysis using Bruker’s Tribo iQ software.

Metallic and ceramic materials have been increasingly used under extreme conditions, such as high temperatures and high stresses. Consequently, there is a need to understand the deformation mechanisms of these materials via in situ micromechanical testing techniques at similar extreme conditions. In this presentation, I will provide several examples on the deformation mechanisms of advanced metals and ceramics, wherein twin boundaries, stacking faults and phase boundaries largely impact their mechanical properties and high temperature deformation mechanisms. For instance, in situ micromechanical testing shows that CoAl intermetallics and TiO2 with certain defects exhibit prominent deformability at room temperature. Furthermore, in situ testing also allows us to examine the deformation behavior of nanotwinned Al alloys and ceramics at elevated temperatures. These studies enabled by Bruker PI 89 in situ nanomechanical testing instrument allow us to probe the fundamental deformation mechanisms of a variety of advanced metallic and ceramic materials.
