Studying Mechanical Behavior of Advanced
Structural Materials

• Motivation
• The fatigue-behavior study is essential for
  structural-integrity analyses. Fatigue properties
  are widely applied to predict/estimate the life
  of the materials used in the transportation
  industry, such as bridges and jet engines.
• The atomic and microscopic mechanisms on the
  degradation of the mechanical behavior in the
  advanced materials, including bulk-metallic
  glasses, nanomaterials, and superalloys, remain
  unclear.
• The synergistic international collaborations
  using
• the in-situ neutron and high-energy X-ray
  diffraction techniques reveal the effect of
  stresses on microstructural evolutions.

• Research Efforts
• The quantitative characterization at the
  multi-scale microstructural levels is necessary
  to understand the plastic deformation, stress
  states, and materials performance.
• In-situ neutron-diffraction experiments examine
  (1) the dislocations dynamics and (2) the
  fracture mechanics of structural and engineering
  materials.

• Impact
• The experiments and theories help us improve the
  reliability and performance of structural
  components and develop new materials.

MSE 676 Neutron Diffraction Fundamental and
Applications

• Promotions and Activities
• The fellowship programs are advertised in
  journals and conferences, such as the 2006
  Materials Research Society (MRS) Fall Meeting.
• The ANSWER-supported publications are 10 (2003),
  11 (2004), 21 (2005), 61 (2006), and 36 (2007,
  Sept.).

• Lecturers from overseas taught students from
  institutions worldwide. The courses and handouts
  were live broadcasted and are archived on-line.

• Professor Tamás Ungár, Eötvös University,
  Budapest, Hungary, taught students at the 2007
  ANSWER Summer School. The lectures are available
  on-line.

Outreach Programs, IMI-ANSWER, University of
Tennessee

• IMI High-School, Female and Minority Students
  Programs, and Neutron Schools
• The availability and new capabilities of the
  Spallation Neutron Source (SNS) at Oak Ridge,
  Tennessee, have been communicated to high-school,
  female and minority students.
• The IMI-ANSWER neutron schools, courses,
  tutorials, workshops, and booths at conferences
  have educated students, postdocs, and faculty
  worldwide.
