In this webinar, guest speaker Dr. Xinghang Zhang (Purdue University) showcases 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 is also being presented by Bruker experts, along with analysis using Bruker’s Tribo iQ software.
This webinar, moderated by Bruker NI Sales Manager Michael Berg, has three parts: guest speaker, product overview, and live demonstration. Prof. Xinghang Zhang (Purdue University) first uses examples from his own research to showcase the in-situ and high-temperature capabilities of the PI 89, Bruker’s versatile SEM in-situ nanomechanical testing instrument. Second, Bruker Applications Scientist Eric Hintsala, Ph.D. briefly presents an overview of the PI 89 product features, capabilities, and accessories. Finally, Bruker Applications Scientist Jasmine Johnson gives a live demonstration of mapping using the PI 89, along with analysis using Bruker’s Tribo iQTM software.
Guest speaker Prof. Zhang focuses on three materials, examining their plasticity and deformability at high temperatures: nano-twinned Al alloys, nanocrystalline CoAl, and flash-sintered TiO2.
Connecting to the use cases presented by Prof. Zhang, Bruker’s Dr. Eric Hintsala explains why the PI 89 is both advanced and versatile, with a modular stage design, increased force range, multi-sample mounting, and quick-swap transducers. He also gives an overview of the many options and accessories available for the PI 89, all of which can be found on the Accessories tab of the PI 89 product page.
Bruker’s Jasmine Johnson finishes out the webinar with a testing and analysis demonstration. Johnson sets up an automated property map (60 indents in 12 minutes) at 600°C on a bond coating between nickel-aluminum and a nickel superalloy using the relevant control software:
She also analyzes equivalent data in the Tribo iQ software, which is an app in OriginPro. Among the TriboIQ capabilities are data corrections and performing a power-law fit for each indent to obtain parameters such as hardness and elastic modulus. Johnson plots and analyzes the data for the indent array in Tribo iQ XPM, showing several different plot views and filters, as well as quantitative analyses.
