| Summary: | Electron beam fuse deposition(EBFD)is a rapidly developed metal 3D printing technology in recent years.The EBFD technology was used to print 304 stainless steel materials.The effects of different accelerating voltages in the process of EBFD on the morphology,density,microstructure and mechanical properties of the forming products were compared.The results show that when the accelerating voltage is 50 kV,there are a few austenite grains in the microstructure.When the accelerating voltage is increased to 60 kV,the austenite grain boundary is completely formed,and the growth continues with the increase of the accelerating voltage.When the accelerating voltage is 60 kV,the comprehensive mechanical properties are the best,the anisotropy is the weakest,and the fracture is ductile fracture. |
