| 英文摘要: |
| The continuous development of additive manufacturing technology enables rapid prototyping of complex structural components. To make the additive
manufacturing Ti6Al4V alloy better applied, the effects of substrate preheating, laser power, scanning rate and subsequent processing on the microstructure and mechanical properties of
Ti6Al4V alloy were studied by domestic and foreign scholars. It was found that the selection of appropriate process parameters and post treatment can improve the comprehensive
mechanical properties. At present, the microstructure of titanium alloy has certain defects, the micropores and unmelted particles in the components hinder the improvement of mechanical
properties. In the future, while solving microstructure defects, the application of additive manufacturing titanium alloys components will be one of the future research directions. |
