International Materials Institute: Advanced Neutron Scattering netWork for Education and Research (ANSWER) Peter Liaw, University of Tennessee, DMR IMI-ANSWER-Japan Research Collaborations on Bulk-Metallic Glasses Motivation  Processing and properties of bulk-metallic glasses (BMGs) have been widely studied. However, their atomic structures still remain mysterious.  Structural models of BMGs are typically based on hard-sphere representations, which offer little direct correlation to the observed properties, such as mechanical behavior.  A further understanding of the local atomic structure of BMGs is critical for developing and manufacturing the next-generation, glass- forming alloys.  Current collaborations focus on the glass- forming ability and fatigue behavior of BMGs. Research Efforts with Dr. Y. Yokoyama and President A. Inoue, Tohoku University, Sendai  Designing and fabricating BMGs.  Using the neutron diffraction on the Neutron Powder Diffractometer (NPDF) at the Los Alamos National Laboratory and Small Angle Neutron Scattering (SANS) at the National Institute of Science & Technology (NIST) to study the atomic structures.  Applying computational simulations to understand the mechanisms. Impact  The collaborations develop new materials and study their properties and potential applications.  The number of IMI-ANSWER-Japan collaborators’ publications is 14.
