Progress in Materials Science, a highly regarded international review journal, has named Terence G. Langdon the “most cited” author in 2005-2008. Langdon is the William E. Leonhard Professor of Engineering in the USC Viterbi School Department of Aerospace and Mechanical Engineering (AME).

The award, issued by the journal’s publisher, Elsevier, was given to Langdon and co-author R. Z Valiev of Ufa State Aviation Technical University, Russia, for their paper, “Principles of equal-channel angular pressing as a processing tool for grain refinement,” published in September 2006 (Volume 51, page 881). This paper has so far received 238 citations.
“This most noteworthy award is, of course, consistent with Professor Langdon being the second most cited materials scientist in the world,” said AME Chair Michael Kassner.
Progress in Materials Science, considered the most authoritative journal in materials science, only publishes review articles. It does not publish regular research papers. The journal has an impact factor of more than 20, which puts it far above regular research journals in stature and influence.
Langdon, a professor of aerospace and mechanical engineering, materials science and earth sciences at USC, is a pioneer in the field of processing and understanding the properties of ultra fine-grained and nanostructured materials. Such materials exhibit far greater strength and toughness than some of their coarse-grained counterparts.
He specializes in the phenomenon of superplasticity, a malleable state in metals similar to the softening of glass at high temperatures. Working with his students, Langdon has greatly reduced the time required to shape metal parts using superplastic forming. Co-author Valiev, director of the Institute of Physics of Advanced Materials in Ufa, regularly visits Langdon and his research group at USC to catch up on collaborative projects. Valiev and Langdon were co-chairs of the First International Conference on Bulk Nanostructured Materials (BNM-2007), held in Ufa in August 2007, and are co-organizing a follow-up conference (BNM-2009) in Ufa in September 2009.

Langdon has a long list of honors and accolades, including the 2008 Blaise Pascal Medal for Material Science, given by the European Academy of Sciences (EAS); an invitation from the Chinese Academy of Sciences in Shenyang, China, to deliver the 2009 Lee Hsun Lecture at the Institute of Metal Research; and winner of the 2007 Albert Sauveur Achievement Award from ASM (formerly the American Society for Metals) International.
He is a Fellow of the Royal Academy of Engineering (U.K.); the European Academy of Sciences; the American Association for the Advancement of Science (AAAS); ASM International; The Minerals, Metals and Materials Society (TMS); the American Ceramic Society; the World Innovation Foundation; and the Institute of Physics and the Institute of Materials in the United Kingdom. He is also an honorary member of the Japan Institute of Metals.
Langdon is the author of more than 500 published scientific papers in peer-reviewed journals with more than 300 different co-authors. He has an h-index of 69, which means that 69 of his publications have each received at least 69 citations.
