Cold and Colder, Nanoindentation Down to -120°C
See PI Cryo in action down to -120°C
In this webinar, Bruker experts demonstrate operando nanomechanical testing down to -120°C using PI Cryo. The speaker, Dr. Douglas Stauffer, first clarifies the motivation for testing from cold to cryo conditions and briefly explains how nanoindentation works. Then, he gives an overview of the PI Cryo instrumentation for in-situ SEM experiments and illustrates its performance with cryogenic testing of an aluminum reference sample. Finally, Dr. Stauffer presents three case studies and answers audience questions.
Presenter's Abstract
During this webinar, Bruker nanomechanical testing expert Douglas Stauffer, Ph.D. discusses in-situ, operando testing from room temperature down to -120°C using PI Cryo for the Hysitron PI 89 SEM PicoIndenter.
Dr. Stauffer first explained the motivation for low-temperature testing and how nanoindentation works. He then detailed Bruker’s cryogenic testing instrumentation, particularly the methods used to minimize thermal drift and noise. To demonstrate performance, Dr. Stauffer showed results from an aluminum reference sample.
He then presented three case studies:
- A 1018 steel, with observation of a transition to more brittle behavior at low temperatures
- PDMS, showing changes in storage modulus with temperature
- A polymer film, with a clear glass transition temperature that could be measured using the PI Cryo
To close the webinar, Dr. Stauffer answered questions from the audience.
