Resonant ultrasound spectroscopy (RUS) is a nondestructive method for studying the elastic properties of solid materials. The elastic constants are sensitive to transformations like first- and second-order phase transitions and microstructure changes; and, in principle, the full elastic tensor can be determined from a single RUS scan. In this talk, the RUS technique is introduced along with demonstrations of its utility within materials research. Furthermore, it will be shown that integration of RUS into neutron scattering measurements provides multiple advantages such as multiscale information, precise temperature tracking, and phase transition identification. Also included are hardware and software developments that serve to improve the experience of end users. A discussion on future research directions is welcome.
