EducationPhD, Materials Science and Engineering, Carnegie Mellon University, 1970. Professional InterestsDr. DeArdo's research involves composition-processing-microstructure-mechanical property relations in structural materials, especially engineering alloys such as microalloyed steels and stainless steels. Of particular interest in his work are thermomechanical processing for microstructural control, texture development for improved formability, mechanical property optimization, the machinability of bar steels and ameliorating embrittlement in a variety of materials. These programs involve the use of hot deformation machines, computer interfacing, a broad spectrum of metallographic techniques, and extensive mechanical testing. Research topics currently being pursued in the Basic Metals Processing Research Institute (BAMPRI)are: (i) the alloy and process design and optimization of advanced high strength coated Dual-phase and TRIP steels for the automotive industry, (ii) methods of achieving grain refinement in heavy gauge HSLA steels, (iii) stabilization, formability and rope control in ferritic stainless steels, (iv) new EBSD-based techniques for characterizing microstructure in high strength multiphase HSLA steels, (v) transmission and scanning- transmission electron microscopy and atom probe - field ion microscopy studies of ultra-fine or nano-structure in HSLA steels. Dr. DeArdo and his colleague, Dr. Garcia in BAMPRI recently made an enormous breakthrough in the steel industry with the development of a non-lead bearing free machining steel. This environmentally-friendly steel offers the unique combination of excellent machinability without lead contamination.

Curriculum VitaeDr. DeArdo joined the department in 1975, became associate professor in 1977 and professor in 1985. He was awarded the Gillette International Post-doctoral Fellowship and spent 1971 and 1972 at the University of Cambridge. In 1973-74 he was senior research metallurgist at the former Jones and Laughlin Steel Corporation. Dr. DeArdo was elected Fellow of the Institute of Materials, London, in 1994 and Fellow of ASM International in 2000. He is also a member of the American Institute of Steel Technology, the Iron and Steel Society of AIME, and the Metallurgical Society of AIME. Since 1989, he has held the Whiteford Chair of Materials Science and Engineering. Dr. DeArdo's teaching includes mechanical and physical metallurgy with emphasis on the boundary between the two disciplines. His courses cover mechanical behavior of materials, the design of structural materials, annealing phenomena, formability, strengthening mechanisms, deformation processing, thermal treatments, mechanical properties and fracture. He has developed numerous contacts with the global metallurgical industry, particularly in the areas of hot deformation, microalloyed HSLA steels and advanced high strength steels. These have led to the establishment of the Basic Metal Processing Research Institute, directed by Dr. DeArdo, within the department.
