Abstract Scope |
Process variables in additively manufactured 3D metal print designs are known to affect their
microstructural evolution, texture and defect structures. In particular, variations in power and
velocity 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
how the solidifying grains grow into the fusion zone. Results obtained from electron backscatter
diffraction will be used to visualize and quantify grain growth direction and grain orientation
gradients as a function of different laser process parameters.
