| Abstract Scope |
Advanced manufacturing techniques enable the creation of complex metallic microstructures
containing nanoscale precipitates of equilibrium and metastable phases. Understanding plasticity
mechanisms and phase stability is essential to unravel the complexity of the deformation
response. In-situ x-ray diffraction (XRD) has been employed to analyze the microstructure
through changes in diffraction patterns. However, the role of interfaces and phase metastability
on the deformation mechanisms remains unclear. This study uses molecular dynamics
simulations to investigate the deformation mechanisms in multiphase Cu-Fe microstructures with
Cu clusters in a BCC Fe matrix and Fe clusters in an FCC Cu matrix under shock loading.
Virtual XRD is used to correlate microstructure changes to diffraction patterns. This talk will
present our approach to understanding the effect of nanoscale precipitates on the deformation
mechanisms and diffraction patterns of multiphase Cu-Fe microstructures. This study is
supported by the Department of Energy, National Nuclear Security Administration under Award
No. DE-NA0003857. |
