| description | An experimental study of process parameter optimization for stainless steel 316L
(SS316L) parts additively manufactured by selective electron beam melting (SEBM) was carried
out. The process parameters for different stages, particularly in the in-fill hatch melting stage, were
optimized in this study. Near-fully dense (>99%) SS316L parts have been successfully fabricated
with well-melted surfaces. Microstructural characterization was performed on the as-SEBM-built
SS316L parts with the optimal process parameters. It revealed that near-equiaxed grains were
formed, which is distinctive from the counterparts additively manufactured by other SEBM
processes. The mechanism for the formation of near-equiaxed grains was discussed in detail. This
paper provides an insight into fabricating SS316L parts with high density and desirable
microstructure via SEBM process. |
