Connor Slone, Ph.D.

Associate
Materials & Corrosion Engineering
Menlo Park

Dr. Slone specializes in failure analysis and prevention with specific expertise in metallurgy and microstructure development, materials characterization, and deformation mechanisms of metals. He has extensive experience with a variety of analytical tools and techniques including metallography and optical microscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), and mechanical testing of materials across a wide range of temperatures and loading modalities.

Prior to joining Exponent, Dr. Slone was a National Science Foundation Graduate Research Fellow at The Ohio State University. He completed his Ph.D. in 2019, and his doctoral thesis focused on the influence of composition and processing on the mechanical response of high entropy alloys. This work included computationally-screened alloy design via calculation of phase diagram (CALPHAD) techniques; thermo-mechanical processing of new alloys; mechanical assessment, including hardness measurement, rate-controlled tensile testing, and high-temperature creep testing; and analysis with electron-microscopy-based techniques such as energy dispersive X-ray spectroscopy (EDS), electron backscatter diffraction (EBSD), and electron channeling contrast imaging (ECCI).

Dr. Slone has also provided characterization expertise for projects involving laser powder bed fusion (LPBF) additive manufacturing, dissimilar metal joints produced by vaporizing foil actuator welding (VFAW), and welded Ni-base superalloys used for high-temperature aerospace and power generation applications.

In addition to his analysis and research experience, Dr. Slone has also served as a teaching assistant for undergraduate and graduate materials science courses and led a practical laboratory course in scanning electron microscopy (SEM) methods.
