In Session 23 of the KLA Instruments Indentation University series, nanoindentation measurement of the yield stress-strain curve is demonstrated using the iMicro nanoindenter on Ti-6Al-4V, and additional experimental results are presented on Ti-64, 3D-printed metals, bulk metallic glasses (BMG) and precious metal alloys.
About This Webinar
Session 23 covers the demonstration of and experimental results from using nanoindentation to characterize the stress-strain curve on steel A516, Ti-6Al-4V, Ti-64. Demonstration by Jennifer Hay of KLA Instruments includes a brief overview of yield stress-strain theory, and then continues to sample loading, recipe setup and discussion of results. Dr. Amit Datye of Yale University discusses his yield stress-strain experiments on Ti-64 and bulk metallic glasses including Zr, Pt and Pd BMGs. Dr. Datye also discusses his work on nanomechanical properties of precious metal alloys, including Au, Ag, Pt and Pd-based ternary, quinary and HEAs, plus an overview of his high-throughput materials discovery methods.
Note: for Session 23, it is recommended to view the following Indentation University webinars as background for the discussion:

About the Speakers
Jennifer Hay is a Senior Applications Scientist for KLA Instruments, specializing in nanoindentation. Prior to joining KLA, she held similar positions at Nanomechanics, Keysight, Agilent, and MTS Systems Corporation. Jennifer has worked in the field of nanoindentation since 1996, advancing standardization while also developing methodology for new applications including thin films, polymers, gels, and biomaterials. Mrs. Hay served as the chair for the MEMS/Nanomechanics technical division of the Society of Experimental Mechanics (SEM), and she has authored many journal articles on nanoindentation, including an invited feature series in the SEM journal Experimental Techniques.
Dr. Amit Datye is an Associate Research Scientist of Mechanical Engineering and Materials Science at Yale University as part of the NanoProbe group. Dr. Datye received his Ph.D. in Materials Science from the University of Tennessee under Dr. George Pharr. His research focus is on additive manufacturing of Ti-64, the development and characterization of bulk metallic glasses precious metal alloys, and high throughput materials. A recent publication prior to this presentation was in Nature: Communications Materials, entitled “Atomic-scale homogeneous plastic flow beyond near-theoretical yield stress in a metallic glass”.
