Nanomechanical Testing Webinars

In-Situ SEM Nanomechanics of Metals and Ceramics at Elevated Temperatures

Learn about high temperature in situ SEM testing of metals and ceramics

Understand the deformation mechanisms of metallic and ceramic materials via in situ micromechanical testing under extreme conditions.

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.

Date: Tuesday, November 22 — 9AM PST | 12PM EST | 6PM GMT+1

Presenter's Abstract

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.

Xinghang Zhang, Ph.D., Professor of Materials Engineering, Purdue University

Xinghang Zhang obtained his Ph.D. from North Carolina State University in 2001. He was a Director’s postdoc fellow at Los Alamos National Laboratory. After spending 12 years at Texas A&M University, he joined Purdue University in 2016. Zhang’s team excels at radiation damage and mechanical behavior of nanocrystalline, nanotwinned, and nanolayered metals and nanostructured ceramic materials. Together with his graduate students and colleagues, they have published more than 300 journal articles. Among more than 20 of his Ph.D. students graduated so far, many have become faculty at university or national laboratories. He is the Chair of the Nanomechanical Behavior of Materials Committee at the TMS, and an associate editor for Science Advances. Zhang has received numerous research awards, including National Science Foundation’s Early Career award and TMS Brimacombe medal. Zhang is an ASM Fellow.
