Intrinsic relaxation in a supercooled ZrTiNiCuBe glass forming liquid
We studied structural relaxation in the bulk metallic glass forming alloy Zr 46.8 Ti 8.2 Cu 7.5 Ni 10 Be 27.5 on different timescales and length scales, with emphasis on the supercooled liquid state. Using x-ray photon correlation spectroscopy, we determined the microscopic structural relaxation tim...

| Sumario: | We studied structural relaxation in the bulk metallic glass forming alloy Zr 46.8 Ti 8.2 Cu 7.5 Ni 10 Be 27.5 on different timescales and length scales, with emphasis on the supercooled liquid state. Using x-ray photon correlation spectroscopy, we determined the microscopic structural relaxation time covering timescales of more than two decades in the supercooled liquid region, down to the subsecond regime. Upon heating across the glass transition, the intermediate scattering function changes from a compressed to a stretched decay |
