Graduate Student Admissions: Please notify your colleagues and associates that the deadline
for graduate student applications for fall enrollment in MSE is February 1, 2015. In certain
circumstances, we may accept slightly late applications, particularly from domestic students.
We look forward to receiving many applications from outstanding students around the country
and the world, who have interest in pursuing their Ph.D. degrees in MSE here at UT.

Graduate Students from the Kyushu Institute of Technology visit UT-MSE (by Kurt Sickafus)This month, we have been honored to host a visit by two graduate students from the Department of Materials Scienceand Engineering (MSE) at the Kyushu Institute of Technology (also known as Kyutech), Fukuoka, Japan(http://www.kyutech.ac.jp/english/about/). The students are Mr. Kazuki Watanabe and Mr. Kenta Imada, both first year
Masters degree candidates in MSE at Kyutech. Both Kazuki and Kenta earned their Bachelor of Engineering degrees atKyutech last year. Their Masters degree advisor is Professor Manabu Ishimaru, who recently moved from Osaka
University to Kyutech. Manabu is an expert in transmission electron microscopy and radiation damage effects insemiconductors and insulators. Both Kazuki and Kenta are at UT this month to perform ion beam irradiation
experiments in the Ion Beam Materials Laboratory (IBML), a new facility developed as a research partnership between
UT and Oak Ridge National Laboratory (http://ibml.utk.edu/). Kazuki and Kenta’s ion irradiation experiments arebeing performed in collaboration with Professors Bill Weber and Yanwen Zhang, who direct the research at the IBML.
Kazuki is performing germanium (Ge) ion irradiations on amorphous Ge targets, to better understand radiation-induced
atomic disordering phenomena. Kenta is performing gold (Au) ion irradiation experiments on nano-structured thinfilms of silicon carbide (SiC). He is interested in radiation-induced amorphization of nanophase materials. Kazuki andKenta visit UT from January 8 – February 4.
Mr. Louis (Lou) Santodonato and Professor Peter Liaw publish research in Nature Communications.

Deviation from high-entropy configurations in the atomic distributions of a multi-principal-element alloy. Nat
Commun 2015; 6 (DOI: http://dx.doi.org/10.1038/ncomms6964).	   full-length article by Louis Santodonato and colleagues tells the story of aThis
uniquely complex class of metallic materials that have come to be known as highentropy alloys. High entropy alloys are compositionally fascinating because they
are composed of intimate mixtures of five or more elements, all in highconcentrations (the model alloy discussed by Santodonato et al. is
Al1.3CoCrCuFeNi). These alloys are structurally interesting because so many
elements lead to highly complex atomic mixing and un-mixing behaviors, as thesealloys are solidified from the melt. Louis and his colleagues used complementary
neutron and X-ray synchrotron scattering techniques to measure multiple orderingparameters in high-entropy alloys over a wide range of temperatures. They also
employed theoretical atomistic simulation techniques to reveal local ordering trends
in the liquid states of these alloys. This work is important because it is anticipatedthat high-entropy alloys will possess exceptional properties in engineering
applications (high strength at high temperatures, ductility, toughness, corrosion
resistance, etc.).
