Variations in ambient and elevated temperature mechanical behavior of IN718 manufactured by selective laser melting via process parameter control

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 ali...
