Conferences and Lectures - John F. McMahon Lecturer

Thursday, November 17, 2016 - 11:20 am
Holmes Auditorium, Harder

George Quinn

Mr. Quinn is a consultant with 47 years of expertise in mechanical properties of ceramics and glasses. He is a world authority on mechanical testing and fractographic analysis of ceramics and glasses. He wrote the definitive book: “Fractography of Ceramics and Glasses” in 2007. The second edition, a major expansion, was just released in May 2016 (NIST Special Publication 960-16e2). He is the sole authored or co-author of twenty-three Military, ASTM, or ISO ceramic documentary standards. He created two standard reference materials for ceramic hardness and one for fracture toughness. He retired from the National Institute for Standards and Technology NIST in January 2009, but continues his affiliation with NIST as a Guest Researcher. He also is an adjunct professor in the Department of Mechanical Engineering of the University of Maryland, Baltimore County. He is a Fellow of the American Society for Testing and Materials and also the American Ceramic Society. Along with Jim Varner, he has taught the short course “Fractography of Glasses and Ceramics” every summer at Alfred University since 1996. He is a collector of ancient Roman glass and has consulted with the Corning Museum of Glass.

Adventures in Applying Fractography to Modern Glass and Ceramic Fractures and to Ancient Roman Glass

Fractography is a powerful tool to aid materials science studies and to solve practical failure problems. Alfred University is a world-recognized center of excellence for fractographic analysis of glasses and ceramics. In this presentation, the author will review how Professor James Varner and the author have carried forward the legacy of Professor Van Derck Fréchette. Alfred is unique in having both a hands-on fractography course in the student curriculum as well as a short course which draws professionals from around the world. The latter course has run continuously for over 40 years and has trained upwards of 700 professionals. This course is considered a model for short courses and has been adopted by other groups.

In this presentation, the author will reflect upon his association with Alfred University and discuss several examples of fractography problems. The new NIST Guide book for fractography will be discussed. Finally, some interesting applications of materials science and fractographic analysis to ancient Roman glass will be discussed.
