Understanding the texture development in selective laser melted pure copper

Selective laser melting of pure copper was carried out to obtain crack-free and dense parts for various laser settings. The crystallographic texture measurements at the top surface showed a change in texture type and intensity when laser settings such as hatch spacing, laser power, and laser scan speed were altered. The texture orientation at the vertical side surface was random despite the presence of a strong texture on the top surface. The texture type and the intensity obtained at the top surface is explained using melt pool geometry and solidification morphology (as shown in Figure 1), whereas the random texture orientation obtained at the vertical side surface is due to multiple re-melting and 900 scan rotation applied between the successive layers.status: publishe
