Joseph C. Tucker, Ph.D.
Senior Associate
Materials & Corrosion Engineering
  • Menlo Park

Dr. Tucker specializes in materials science and metallurgical engineering with specific expertise in aerospace applications. He applies his expertise to failure analyses of all types as well as intellectual property disputes, including validity and infringement. His experience is with a variety of alloys (aluminum, copper, steel, superalloys, and titanium to name a few) and various investigation methods (fatigue testing, tensile testing, microscopy, and simulation).

Dr. Tucker has spent nearly a decade researching a variety of material science and metallurgy areas. Previously, he was a contract research scientist at Air Force Research Laboratory, focusing on jet engine rotating parts and aerospace structural materials as it relates to aircraft failure mechanisms. He has specific expertise in fatigue, corrosion, creep, metallurgical processing (casting, forging, rolling, heat treating), material selection for structural applications, and welding techniques for weld joint microstructure vulnerability and welding failure. His doctoral work focused on analyzing nickel-based superalloy fatigue for aircraft turbine engine rotating part failure. His research led to improved alloy development methodologies that extend component service life.

Dr. Tucker has presented and published in numerous peer-reviewed journals and conferences, including: Modelling and Simulation in Materials Science and Engineering, Acta Materialia, Metallurgical and Materials Transactions, MS&T, and TMS. Dr. Tucker is also a voting member on the ASTM Metallography committee with jurisdiction over 35 standards.
