| 摘要： | 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 single/double stage gas gun able to achieve impact velocities of 4.5 km/s and a compression/tensile 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. |
