2007 ASM Oak Ridge Chapter Educational Symposium
Neutrons for Materials Science and Engineering
April 18, 2007
Spallation Neutron Source, Oak Ridge
National Laboratory, Oak Ridge, TN
Synopsis
Meeting the educational needs of students, faculty, engineers and scientists in universities, industry and laboratories and aiding American economic competitiveness are important to the ORNL neutron scattering community at the Spallation Neutron Source and the High Flux Isotope Reactor. These ORNL user facilities, and the state-of-the-art user facilities at other national laboratories funded by the U.S. Department of Energy, are shared with the science community worldwide and offer some technologies and instrumentation that are available nowhere else. Each year, these facilities are used by thousands of researchers from universities, other government agencies, and private industry. The new capabilities at HFIR and SNS will greatly expand the impact of neutron scattering.
Neutron scattering is an important scientific technique to characterize materials of all classes – polymers, soft materials, metals and alloys, and ceramics for such applications as fuel cells, hydrogen storage, biomedical and bio compatible, aerospace, nuclear power, and electronics. Many of the new facilities provide sample environments that provide for measurement at non ambient conditions of temperature or pressure, under applied tensile/compressive/torsion load or in high magnetic fields.
The program of the ASM Educational Symposium on Neutrons for Materials Science and Engineering has been developed to expand the awareness of North American students and faculty involved in materials science and engineering studies to the diverse applications of neutron scattering and to the expanding facilities in North America. The Symposium is also open to scientists and engineers who wish to obtain a broad overview of the many applications of neutron scattering to studies of materials.
The symposium will include ten talks beginning with the basics of production of neutrons and their uses, an overview of neutron scattering and diffraction methods. Subsequent presentations will present how neutrons are used to study phase transformations, engineering stresses, materials deformation behavior, polymer and soft materials, biomedical and bio related materials, studies of fuel cell and hydrogen storage materials, and a engineering and industrial applications of neutron scattering. Tours of the recently commissioned Spallation Neutron Source and the upgraded High Flux Isotope Reactor sources and associated neutron scattering instruments will culminate the Symposium.
A companion event to the ASM Education Symposium is the Neutron Stress, Texture and Phase Transformation for Industry Workshop that will begin with an overview session providing an international perspective of the contributions of neutron facilities currently utilizing engineering diffraction techniques for industrial related studies. The poster session at lunch time will provide an opportunity to learn more the research carried out at these neutron facilities in the U.S. and overseas as well as to continue discussions about specific needs of industry attendees. Presentations by speakers affiliated with industry will follow; these will describe relevant ongoing research currently that is assisted by the information made available by neutron scattering.
ACNS is held at one of the major neutron scattering facilities in the US in June of even-number years [2004 and 2006]. ANSWER will work with ACNS to enhance the international participation in the materials science session with a focus on mechanical behavior studies. Another symposium on “neutron-diffraction characterization of mechanical behavior” is already planned at the 2005 TMS Annual Meeting by the PIs. Thereafter, a biennial international symposium on this topic will be hosted by ANSWER at the Annual TMS Meetings [2005 and 2007]. A four- to six-session symposium will be organized on neutron-diffraction characterization of mechanical behavior. The symposium will provide an international forum for the presentation and discussion of recent experimental and theoretical modeling results. The symposium is intended to bring together neutron diffraction scientists and potential users to further enhance the neutron diffraction research activities.
ANSWER interacts with many materials-research societies and neutron-scattering societies in organizing and hosting the symposia, workshops, and neutron schools. By hosting ANSWER symposia and workshops in conjunction with other international materials-research conferences, such as the American Conference on Neutron Scattering [ACNS] and TMS Annual Meeting, much broader technical impacts and a financial leverage are expected.
Our vision is to offer graduate students a unique set of international education and research-training opportunities and to produce Ph.D. graduates with the world-class knowledge, experience, and leadership in the area of Neutron Scattering Materials Research. The following activities are currently being conducted and planned to enhance the neutron education at UT and other participating universities in the US to an internationally competitive level.
The scope of the ANSWER’s educational activities ensures that the impact of the IMI reaches beyond the UT and other participating institutes. Our outreach efforts include the K-12 science education, minority outreach, and public awareness. ANSWER provides colloquia, demonstrations and tours of UT, HFIR, HTML, and SNS for high-school students and teachers, including the underrepresented students from the southeastern region of the US. These activities are organized in conjunction with international activities, such as Workshops, Symposia, and Neutron Schools. Educational materials are developed by a team consisting of materials specialists from the participating institutions, an educational outreach specialist, and a Web editor.

TMS Conference 2006
TMS Conference 2005
ANSWER organized an international symposium on “Neutron Diffraction Characterization of Mechanical Behavior” at the TMS Annual Meeting in San Francisco, February 13-17, 2005. A total of 70 papers were presented by leading scientists from 13 different countries [USA, Australia, Austria, Canada, Czech Republic, France, Germany, Hungary, Japan, Russia, Sweden, Switzerland, and United Kingdom].
Specific topics included:
[1] Polycrystalline deformation mechanisms,
[2] Mechanical behavior of composites,
[3] Residual stresses,
[4] Structure-property relationship studies, and
[5] Advances in instrumentation and data acquisition/analysis scheme. The symposium consisted of 7 sessions [3.5 days] and brought together neutron diffraction scientists and potential users to further enhance the neutron-diffraction research activities at the international level.
At the conference, the 2nd ANSWER workshop was held.
The specific agenda for the workshops will include:
[1] Identifying areas of important and innovative research for joint research programs,
[2] Progress reports on the cooperative research projects by senior members,
[3] Progress reports by ANSWER Fellows and evaluations,
[4] Selection of new Fellows,
[5] Planning of the Exchange Programs for the following year, and
[6] Preparation and scheduling of neutron-beam time proposal writing for the collaborative research projects in the upcoming year.
MECA SENS Conference
ANSWER co-sponsored an international symposium, the 3rd MECA SENS conference on stress evaluation by neutron and synchrotron radiation, from October 17-19 in Santa Fe, New Mexico. The aim of the MECA SENS conference is to bring together scientists from the academic world and industry to address the field of stress measurement using neutron and synchrotron X–ray radiation. The first two conferences were each attended by more than 100 scientists from the engineering-diffraction community. Principal subject areas include residual stresses due to processing and use, materials responses to mechanical perturbations, neutron and synchrotron instrumentation, etc. At this conference, there will be a business meeting to discuss the on-going and future international research collaboration by ANSWER.
