Figure 3: The probability 𝑓 𝜔 /( 1 𝑓 𝜔 ) of the NP flow passing through the plane intergranular boundary of thickness 𝑙 g b as a function of 𝑞 2 𝑙 g b . (1) 𝜌 2 𝑣 2 / 𝜌 1 𝑣 1 = 0.6; (2) 0.7; (3) 0.75; (4) 0.8; (5) 0.85. The experimental points for specimens: 1 ( ); 2 (□); 3 (△); 4 (*); 5 (○); 6 (×), and a specimen prepared with a different procedure ( ).
