Magnetoelastic Measurements in High-Speed Steel Torque Transducers - Part II

Speaker: Professor Mark S. Boley
Date: March 26, 2010 (Friday)
Time: 4 PM
Venue: 205 Currens Hall


In this presentation, I will follow up on my colloquium (1/29/2010) earlier this semester with my explanation of some of the basic physics background and the historical development of current magnetoelastic torque sensing technology from the perspective of undergraduate-level physics. The group of measurements that are fundamental to understanding the interplay between the magnetic field and the elastic field in these high-alloy steels will also be discussed, along with an explanation of the instrumentation used. While the earlier colloquium centered around the macroscopic group of measurements on these samples, I will only briefly review these results in the current presentation and spend the majority of the time in discussion of the microscopic measurements on these samples using the magnetic force microscope (MFM). A brief overview of the principles of MFM will also be presented. Special attention will be given to the many opportunities that this fairly low-budget research provides for both undergraduate and graduate students to develop basic physical measurement and instrumentation skills that are so essential in any research connected to industry.

About the speaker: Dr. Mark Boley is a professor and the Interim Chair of physics at Western Illinois University. He is a condensed matter experimentalist who uses atomic force/magnetic force microscopy, Raman spectroscopy and magnetoelasticity to study magnetic materials, superconductors and nanomaterials.
