Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The influence of powder preheating on powder blowing, critical scanning speed, and surface quality in Electron Beam Selective Melting (EBSM) technology was investigated. Results shown that the mixed 316L stainless steel powder with 60% gas-atomized powder and 40% water-atomized powder does not only have a proper critical scanning speed which avoid the powder blowing, but also have a good fluidity and a suitable forming ability. The critical scanning speed increases with the increasing powder preheating temperature, and the optimal preheating technology of the mixed 316L stainless steel powder is 800 □ for 60 s.
