UNIVERSITY OF TENNESSEE REPORT
In 2007, the AGMA Foundation awarded a grant to the University of Tennessee for examining “In-situ Measurement of Stresses in Carburized Gears via Neutron Diffraction.” The study demonstrated that neutron diffraction methods have the potential to measure both the residual and operating stresses in gears. The data for statically loaded gears had sufficient resolution to show changes in d-spacing in the carburized layer as a function of tooth load.
