Figure 4
A scanning electron microscope image displays spherical particles, with a particle size distribution graph showing D 10 as 21.93 micrometers, D 50 as 44.27 micrometers, and D 90 as 78.57 micrometers.The left panel shows a scanning electron microscope image of spherical powder particles. The right panel presents a particle size distribution graph with D 10 as 21.93 micrometers, D 50 as 44.27 micrometers, and D 90 as 78.57 micrometers. A histogram indicates most particles fall within 20 to 45 micrometers at 43.61 percent, followed by 45 to 75 micrometers at 36.73 percent, and 75 to 100 micrometers at 8.89 percent. Very small fractions are observed below 20 micrometers, and 3 percent are within 100 to 200 micrometers.

Virgin powder Aluminium 6061-RAM2C SEM image (a) and PSD analysis (b). The image was taken with the SEM - Tescan VEGA3 (magnification: 1,000×) and the PSD analysis was done using the 3P Instruments Bettersizer 2600
