Study of fragmentation and ultrasonic flow impacts of several metal-based alloys
Abdulrahman Sumayli
University of Hull, UK
We present a number of highlight cases in our recent projects funded by the Royal Society and the EPSRC. Our focus
is to study in real-time and in-situ dynamic evolution of solidification microstructures under ultrasonic waves and
pulse magnetic fields. We have used the speciality beamlines from the Diamond Light Source, Advanced Photon Source,
European Synchrotron Radiation Facility, and Swiss Light Source for our studies and worked closely with the relevant beamline
scientists. We also used high performance supercomputer, viper, housed at Hull University to process and analyse the many
hundreds of TB data acquired from the experiments. Our research demonstrates that real-time and in-situ visualisation of
the dynamic microstructural evolution is absolutely essential for elucidating some of the ambiguities or missing links in the
classical theories concerning the solidification processes of metal alloys. Real-time evidence shows that the shock wave created
at ultrasonic bubble implosion and the pinch stresses produced by the electromagnetic pulse are very effective in causing the
fragmentation of dendrites or intermetallic phases, promoting greatly the grain multiplication effect and therefore enhancing
grain refinement.
