When a best-presentations winners envelope was opened at the
annual meeting of the Minerals, Metals and Materials Society (TMS) in
San Antonio, researchers from USC Viterbi School Prof. Terry
Langdon’s group had taken the top two honors in their category.
The TMS meeting included the Fourth International Symposium on Ultra
Fine Grain materials, at which researchers presented more than 120
papers on “on all aspects of science and technology of
ultrafine-grained (UFG) materials produced by Severe Plastic
Deformation (SPD) techniques.”
materials — new structures for familiar metals like aluminum — are
attracting intense research attention worldwide because of their
remarkable properties compared to the familiar coarser-grained forms,
including extraordinary strength and hardness. Langdon's lab is a
center of research in the area, and its latest studies attracted
attention at the symposium.
Judged best oral presentation was “Creep Behavior of an Al-7034
Alloy Processed by ECAP,” by post-doctoral student Cheng Xu and
Langdon, presented by Xu.
The runner-up was “The Significance of Cavitation in a Superplastic
Aluminum Alloy Processed by ECAP,” by Xu, Langdon and graduate student
Megumi Kawasaki, presented by Kawasaki. “I was so surprised we both got
(“ECAP,”or Equal-Channel Angular Pressing” is a new
technique used break down crystalline structures in metals, creating
materials with new and useful properties.)
Langdon, who has been at USC since 1971, holds appointments in
the Viterbi Department of Aerospance and Mechanical Engineering,
the Mork Family Department of Chemical Engineering and Materials
Science , and the College of Letters, Arts and Sciences' Department of Earth Science.
In 2003, he was appointed to the William E. Leonhard chair of
