Abstract

The x-ray free electron laser (XFEL) enables probing a highly compressed material response at the subnanosecond timescale. We exploit the ultrafast XFEL pulse to combine reflection x-ray diffraction and laser-driven shock compression to perform a study of the phase transformation and stability in Fe and Fe-Si alloys. Our approach enables us to observe that solid-solid phase transformations occur in Fe and Fe-Si8.5wt% in ≤130 ps at ∼130 GPa; no transformation is observed in Fe-Si16wt% up to 110 GPa. Density functional theory calculations predict similar phase relations.
