This project investigated the micro-mechanisms of dynamic deformation in heterogeneous materials containing multiple FCC, BCC phases while subjected to extreme loading conditions. The research program was primarily conducted using testing facilities at UNSW Canberra a convertible singledouble stage gas gun able to achieve impact velocities of 4.5 kms and a compressiontensile Hopkinson bar. Diagnostic equipment to monitor the in-situ deformation included a 4-point Photon Doppler Velocimetry PDV and a variety of high speed cameras e.g. Phantom. The deformed microstructures were analyzed via SEM EBSD, TEM and X-Ray analyses. These techniques collectively provided a comprehensive understanding of how microstructural features affect the overall dynamic mechanical response of simple heterogenous materials.
