| Abstract Scope |
Process variables in additively manufactured (AM) 3D metal print designs can affect their microstructural evolution, texture and defect structures. In particular, variations in laser parameters such as power, velocity and hatch spacing are known to affect melt pool geometry in 316 stainless steel parts built with laser powder bed fusion. Consequently, it is expected that these parameters will also directly affect grain growth behavior and orientation evolution. Results obtained from electron backscatter diffraction will be used to visualize and quantify grain growth direction and grain orientation gradients on AM parts built with various laser process parameters. |
