| 總結: | Effects of re-melting strategy on densities and mechanical properties of AlSi10Mg
samples fabricated by selective laser melting (SLM) were investigated. Strategies of same and
opposite re-melting routines based on the alternative stripe scanning routine were performed. The
densification behaviors of the SLM manufactured AlSi10Mg samples with different strategies
were characterized by a solid densitometer. Tensile strength and elongation were also measured
and compared with the samples produced with simple stripe strategy. The results show that remelting strategies result in insignificant increase in the densification and slight decrease in ultimate tensile strength of the SLM components. However, great increase in elongation is obtained by remelting. Furthermore, the same or opposite directional re-melting scanning witnesses no
significant difference in results. |
