TL;DR: In this paper, the dynamic interactions between the ultrasonic bubbles/acoustic flow and the solidifying phases in a Bi-8% Zn alloy were investigated using the ultrafast synchrotron X-ray imaging (up to 271,554 frame per second).

TL;DR: In this paper, a polycrystalline Ni-base superalloy was developed for land-based high temperature applications, such as isothermal forging dies and industrial gas turbines.

TL;DR: In this paper, the highly dynamic behavior of ultrasonic bubble implosion in liquid metal, the multiphase liquid metal flow containing bubbles and particles, and the interaction between ultrasonic waves and semisolid phases during solidification of metal were studied in situ using the complementary ultrafast and high-speed synchrotron X-ray imaging facilities housed at the Advanced Photon Source, Argonne National Laboratory, US, and Diamond Light Source, UK.

TL;DR: The hardware and software components for data collection and image analysis on IMAT are surveyed, and a step-by-step procedure for operating the instrument for energy-dispersive imaging is provided using a two-phase metal test object as an example.

TL;DR: In this article, the fatigue fragmentation of dendritic structures of a SCN-5wt.% Camphor transparent alloy in an ultrasound field was investigated systematically using high-speed imaging.
