AbstractIn-situ high temperature measurement in a scanning electron microscopy (SEM) environment is an important technique for exploring the microstructure evolution and crack propagation within refractory materials and other advanced alloys. In this paper, in-situ tensile fatigue experiments under SEM environment at room temperature and elevated temperature are performed for studying the fatigue performance and crack propagation process of selective laser melting (SLM) additive manufactured Al-Si10-Mg materials. Firstly, in-situ SLM additive manufactured Al-Si10-Mg fatigue tensile samples are prepared, and micro-CT are employed for the characterization of void defects within SLM additive manufactured Al-Si10-Mg with different laser scanning speeds and laser energy; Secondly, in-situ fatigue experiments are carried out under SEM environment at 25 degrees C, 100 degrees C, 200 degrees C, 300 degrees C, 400 degrees C, 500 degrees C and 600 degrees C, respectively. The fatigue mechanical behaviors, microstructure evolution and crack propagations of as-fabricated Al-Si10-Mg samples are characterized. Finally, micro-CT tomography 3D imaging techniques are employed for exploring the link between SLM defects and fatigue performances.
