a The normalized size variation of the particles/grains located at positions A-F as shown in left inset under the processing parameters of P0 = 20 W, v = 100 mm/s. Final geometries of corresponding particles/grains are presented in insets gA–gF; b the normalized size variation of the particles/grains located at position A as shown in left inset under various processing parameters. Final geometries of selected particles/grains are presented in g1–g5
