摘要: The present study considers the effects of process parameters on the microstructural development and mechanical properties of SLM Inconel 718. A continuous scanning strategy was used in conjunction with changes in laser spot size to emphasize texture development in the samples; it was found that aligned laser scan vectors (continuous scans) enhanced the crystallographic and morphological texture that forms during solidification when compared to multi-directional scan vectors (island scans). Although room temperature …
