Scope In 2012-2013 the diffraction community celebrated 100 years since the prediction of X-ray diffraction by M. Laue, and following his suggestion the first beautiful diffraction experiment by W. Friedrich and P. Knipping. To acknowledge the importance of the diffraction discovery, the United Nations Education, Science and Culture Organization (UNESCO) declared 2014 the International Year of Crystallography. The significance of techniques based on the analysis of the diffraction of X-rays, neutrons, electrons and Mossbauer photons discovered later, has continued to increase in the past 100 years.

The aim of this symposium is to provide a forum for discussion of using state-of-the-art neutron and X-ray scattering techniques for probing advanced materials. These techniques have been widely used to characterize materials structures across all length scales, from atomic to nano, meso, and macroscopic scales. With the development of sample environments, in-situ experiments, e.g., at temperatures and applied mechanical load, are becoming routine.

The development of ultra-brilliant third-generation synchrotron X-ray sources, together with advances in X-ray optics, has created intense X-ray microbeams, which provide the best opportunities for in-depth understanding of mechanical behavior in a broad spectrum of materials. Important applications include ultra-sensitive elemental detection by X-ray fluorescence/absorption and microdiffraction to identify phase and strain with submicrometer spatial resolution. X-ray microdiffraction is a particularly exciting application compared with alternative probes of crystalline structure, orientation and strain. X-ray microdiffraction is non-destructive with good strain resolution, competitive or superior spatial resolution in thick samples, and with the ability to probe below the sample surface. Advances in neutron sources and instrumentation also bring new opportunities in neutron scattering research. In addition to characterizing the structures, neutrons are also a great tool for elucidating the dynamics of materials. Because neutrons are highly penetrating, neutrons have been used to map stress in engineering systems. Neutrons have also played a vital role in our understanding of the magnetism and magnetic properties. Specialized instruments have been built to gain physical insights of the fundamental mechanisms governing phase transformation and mechanical behaviors of materials.
The application of those techniques, in combination with theoretical simulations and numerical modeling, will lead to major breakthroughs in materials science in the foreseeable future that will contribute to the development of materials technology and industrial innovation.

Some of the areas (but not limited to) to be explored:

1. Deformation and fracture
2. Texture and recrystallization
3. Analyses of complex, nano-crystalline and disordered materials
4. Spatially resolved measurements at different length scales and 3-dimensional methods
5. Time-resolved measurements of materials processing
6. Characterization of surfaces, interfaces and thin films
7. Theoretical modeling and simulations
8. Phase transition, evolution and critical scattering
9. Diffuse scattering studies of fundamental materials properties
10. Mechanical property characterization, with an emphasis on measurements at the nano- and micro-scale
11. Industrial applications
12. New experimental and analysis methods

Full-length papers are planned to be published in Metallurgical and Materials Transactions A.
