Abstract: Synchrotron radiation-based techniques have become a powerful and advanced tool for studying the structure of materials, especially disordered materials. We report some applications of synchrotron radiation-based techniques in studies of the atomic structures of disordered alloys and liquids, pressure-induced phase transformation in disordered alloys, and the mechanical behavior of disordered alloys. With the development of the third generation Shanghai Synchrotron Radiation Facility (SSRF), many researchers in China will explore and employ its advanced facilities for multidisciplinary research. The SSRF should play a positive and far-reaching role in the promotion of scientific research work in China.
