| Abstract_FL | Additive manufacturing is a new manufacturing technique that integrates laser,digitization,materials and other disciplines.It has the advantages of dimensionality reduction manufacturing,complex forming,and high material utilization.It is one of the most promising techniques in the field of material processing.Metal additive manufacturing technique has been widely studied and applied in the aviation field.The research on the additive manufacturing of aviation metal materials by domestic and foreign scholars continues to deepen.AECC Additive Manufacturing Technology Innovation Center has carried out a quantity of research and obtained some data from the four factors of metal additive manufacturing:microstructure,defects,surface and configuration.Some phenomena and laws have been found,including the characteristics and influencing factors of microstructure continuous growth;influence of the structure on mechanical properties;the characteristics and causes of common defects(pores,cracks,incomplete fusion)in additive manufactured typical materials and their influence mechanism on mechanical properties,especially fatigue properties;the relation between surface roughness and forming angles,and the influence of surface states on fatigue properties;factors influencing configuration of metal additive manufacturing.Finally,the problems existing in the development of metal additive manufacturing are summarized,and the suggestions for future research and development are put forward. |
