Illinois Metallurgy, Microscopy, Failure Expert #44107

I have 43 years of experience, and specialize in the field of metallography and failure analysis with specific knowledge in the areas of fractography, microstructural interpretation and physical metallurgy. I have published on such topics as metallography, failure analysis and fractography. I have testified on quality of soldered pipe joints, discrimination between wire drawing technologies and galvanized coating thickness versus service life. I was hired by a government regulatory commission to critique the study of the lower head of a nuclear generating station reactor as to how hot it got in service. I suggested that selective etching of the stainless steel cladding and quantitative measurements of the carbides and delta ferrite would have allowed much more precise estimates of the temperatures experienced at the 15 locations tested. I obtained a set of specimens and did the testing which proved to be far more precise than what was done by other lab experts.
