| 英文摘要 | Oxygen is crucial in influencing the microstructure evolution of selective laser melted (SLMed) Ti-6Al-4V, significantly impacting its applicability in various sectors. Therefore, this study investigates the influnce of oxygen on microstructure evolution, particularly alpha ' martensite transformation and refinement mechanisms. Four alloys, Ti-6Al-4V-xO (x = 0.11, 0.16, 0.21, and 0.25 wt%), were fabricated by the SLM process. The martensite start temperature (M-s) of Ti-6Al-4V, as evaluated by computation, is 656.8 degrees C, and oxygen was found to increase the M-s by about 10 degrees C per 0.1 wt%. The SLMed alloy samples exhibit [001](beta) growth texture along the build direction. Crystallographic analysis of martensite morphology suggests internal twinning on {10 (1) over bar1} planes as the lattice invariant strain, which becomes more predominant with increasing oxygen content. Refinement of alpha ' martensite plates by oxygen is due to increased lattice distortion, reduced prior beta grain size, and oxygen segregation to beta grain boundaries. Our findings contribute to improving the understanding of the effect of oxygen on the transformation mechanism of alpha ' martensite during SLM of Ti-6Al-4V. |
